Vodacom Poor Service

My 79 year Mother recently visited the Vodacom 4U store in Greenstone and dealt with the customer service agent by the name of Chester. Her contract was due for an upgrade, she however wanted to see if she could get a package at a cheaper rate than she is now paying even if it meant downgrading on a device. The consultant ignoring my Mothers request bul**** her into taking a Redmi device that is costing more a month. The device unopened I called Vodacom Customer Services who informed me that I can return the device to the store. When I visited the store last week Wednesday and dealt with the same consultant he advised me that we could not return the device. In an attempt to help everyone out I agreed to transfer the contract into my name. In order not to incur any additional monthly expenses I then asked for a data sim card that would cover my needs with the idea in mind that I will cancel my home internet and use the Vodacom data sim card instead. I was offered a 250GB data sim card for R299 a month which would suit my needs perfectly. I enquired if I could use my current MTN sim card as my main number and use the Vodacom sim card for Data as the device takes two sim cards and was advised that this would not be a problem. I was asked to go to another consultant in store to set up the phone. On completion I was told that it would cost me R180.00 for the setup. It would have been appreciated if I was made aware of this cost not to mention the fact that the phone was still not working. I was told to put the sim card in the phone in an hour and it should work. This was not the case. It is now a week later. I have visited the store and am now being told that the contract that was sold to me cannot work in a cell phone and I need a router that takes a sim card in order for the sim card to work. I was politely told by Chester the Vodacom 4U service agent to go across to Incredible Connection and purchase one as there is nothing he can do to assist me or the alternative is that he can offer me 60GB of Data at the same price. This is not what I signed for. I signed for 250GB of data. When I expressed the fact that this is simply unacceptable he assured me that he will sort the problem out with head office. When I called him yesterday to find out what is going on he assured me that the problem was being sorted out and that I should try the sim card again this morning. When I tried the sim card this morning it was still not working thus after my account was debit of R358 last night. When I tried to contact him this morning to find out what the issue is he advised that he is not at work. I then contacted Vodacom Customer Services and spent over and hour explaining my situation to two different agents I was told to go back to the store. I cannot understand how I am being expected to incur costs for an error that was made by Vodacom and there is simply nobody that is willing to assist me to get this problem rectified. Disgusting!!
