HORRIBLE, HORRIBLE MTN!!!!!!!!!!!!!!!

I am greatly dissatisfied and disappointed at the type of service i have been receiving from MTN store Sandton City. I took out a contract on the 10-09-2018 for a Nokia phone and I was advised that the store does not have the stock for the phone i was looking for. I was not happy to wait for the phone but because i wanted the said phone with Mtn, I was okay with the SLA. On the 17-08-2018 i then called the store to find the progress of delivery and the sales consultant told me that they are still waiting for the stock. On the 19th the consultant in question called to say that they will be receiving stock on the 20th or the 21st and will call when the stock has arrived. When i got to the store on the 21st at about 17: 00 i was then told that the driver wont be making deliveries as promised. Again, the consultant reassured me that I would have the phone by Saturday the 22nd as he was gonna arrange something with another store and that I will have the phone as promised. i decided to give them a chance and when i called the store on the 25th I was shocked and appalled to learn that the phone in question was still not there and I was told by a lady consultant who refused to give me her name that nobody is forcing me to buy the phone with Mtn and was ready to cancel the deal. Firstly, she was not willing to come up with a solution and told me that I had to wait for the phone again for another 7 working days as there was nothing she could do for me. Secondly, how am I supposed to know Mtn's internal process' as a client?!!! A guy manager saved the day and told me that I will get the phone on 27-09. As I wait and see. To say this has been a terrible experience with a provider is an understatement.
