MTN Appalling customer service

Just experienced the most appualing customer service in my Life from MTN vangate mall. Went into store on the 27th November with the intentions of taking out a contract. Checks were done and I was told I qualify I just need to bring my documentation, at the time the device I wanted was low in stock and was advised by the agent assisting Mikhail that he would keep it asside, as the process of approval would take 24 hours, bare in mind today is a week later. Went into store the following day submitted my documents to a lady named Yusrah who then informed me it would take 24 hours for the approval and she would call me the next day, again I ask the lady if the device I asked for has been kept aside, she says to me not to worry there's a lot of stock. Following day I don't hear anything until I call, bare in mind you need to call the store like 7 or 8 times before you getting through to someone, I get through to her and tells me that my ID copy is not clear, without worries I send the ID copy, don't know how I wouldve known if I hadn't called in. She then assures me she'll send it through and call me back. She then emails me to say oh by the way I checked we don't have the device you wanted turns out Mikhail did not put it aside, there's only 1 left which is kept aside for another customer, God knows what the difference between me and that customer, when she was the one who advised "theres a lot in stock". she then tries to sell me a different device instead. later that day I decide to go into store this is now on day 3,when I arrive she checks and tells me it turns out we need your banking details, bare in mind these are all the documents I've given to her already. Day 3 I call in, seeing that it's my job to do a follow up and I speak to the initial guy who assisted me Mikhail, he apologies to me and says it's been approved but he still needs to order the device. I ask him to cancel the application as I've contacted the store in V&A waterfront and they have got stock but I need to request vangate to cancel on their end and submit with them, as I was told that they could could get the entire process approved and I'd receive the device within a few hours at MTN waterfront, Mikhail insists the only reason the Waterfront staff member had said that, was because the staff member wanted the sale, the process would be longer at the waterfront as Vangate had already got the contract approved, he assures me that I should have the device by Tuesday latest. Monday I call just as a follow bt I'm told he will call me back as he is busy with another client. He calls me and says the device is ready for collection, I go into Store and Im told that he is not there but get assisted by a lady named Sharene, I tell her I'm going to be using a Vodacom Sim on the device as discussed with Mikail she tells me that that I need to port my number to MTN which will take up to 24 hours meaning that once again I need to wait till the number ports over to MTN before I get the device. 24 hours later again I call in and Mikhail says he has no idea why she told me to port as I could use my Vodacom I'm the device without porting my number. He then assures me that he is going to cancel the port and get back to me before he goes home, he doesn't call me as promised so I decide to not call in. The next day which is today I call in and I'm told his not at work so I request to speak to Sharene who assist me with the port and who's favorites words are "I don't know" she tells me that the port was canceled, vodacom has rejected the port as my number is still on contract with them, says she's contacted vodacom and they have porting issues and will call them back later. I call Vodacom myself and they confirm that my contract with them has been canceled on 30th November and the port was approved on their end on 2nd November and if the port needed to be canceled it needs to be done on MTN's side, when asking if they are experiencing any porting issues the lady advised No, a complete contradiction to what MTN has advised. It's been a week and a day later and I am sitting with this Dilemma without a device with MTN. You would think for someone bringing business to the company would be valued yet it seams they're trying their best not to take my business. I regret canceling my contract with Vodacom had no Idea this is what MTN customers have to deal with. I'm completely shook and disgusteed in this poor customer service and wouldn't recommend MTN to any of my friends or family. What a terrible experience!
