Shocking customer service from Telkom Mobile

I was warned about Telkoms ****py service.. Yet I still decided to give them a chance.. 3 and a half weeks ago, I went online on the 10th of Sept and app**** to take up a mobile device contract with Telkom.. The call centre phoned me on the 11th, took my details and boom! a week later on the 19th I received the device and sim card.. I thought, WOW.. good service.. I then realised that the phone I ordered didn't have the dual sim feature (Rather, the phone has 2 models and the model that Telkom had on the contract wasn't a dual sim phone) And then the nightmare began... I phoned Telkom on the 20th and said I would like to return the LG Stylus 3 and take the Huawei P10 lite instead which was a dual sim phone.. I was told they will collect the LG and then I need to do a new application for the Huawei.. I was a little irritated, but I agreed since that was their policy.. 3 days later, no one had phoned me.. so I call back on the 23rd to check what's happening and I am told there is no request on the system.. so I AGAIN explain the whole thing and ask that they collect the LG so that I can place the new order. I was apologised to and the call centre agent promised me that on Tuesday the 26th they will collect the LG and hand the Huawei to me at the same time.. Tuesday comes and goes.. I decide to call them on the 27th to follow up and then I am told that they dint have stock of the black Huawei that I asked for and so my order is on hold.. (yet no one called me to tell me this) so I then say I will take the gold colour that is in stock.. The next day on the 28th, the LG is finally collected from me.. But no sign of the Huawei.. I get ANOTHER call that afternoon of the 28th to do the order for the Huawei since the LG has now been collected (Meanwhile I thought my order was put through last week already because of the whole black and gold saga) I take a deep breath and I give my details AGAIN and I am told I will get my phone in the next 5 to 7 days.. Today the 4th of Oct, I decide to phone Telkom to follow up and see how far my order is and I am told that there is no record of my order since the LG stylus 3... I am shocked and disgusted with the service from Telkom. I have asked on numerous occasions to speak to a manager and for my order to be escalated yet nothing has happened and nobody bothers to call me back.. Telkom Mobile, you advertise these amazing packages but how about assisting someone to actual get the package??
