MTN taking advantage of a pensioner

Completely upset with what MTN has done to my pensioner mother. Contract was up, so she went in-store (in November last year) and asked for a month to month package WITHOUT A DEVICE (so she could cancel if necessary). Was offered a black Friday deal with 40 gigs data per month. The salesman still called me to confirm my moms requirements and I explained that she is a pensioner with financial insecurity and therefore cant be tied into a contract with a device. He then suggested the package and got her to sign everything. She received the 40 gigs once-off and since then she has been having to buy her own data as she receives so little data per month. She placed a query 1- ********** 4138 and is still not receiving her data. Since then she has been in hospital for 2 surgeries and is now bed bound for the next 3 months. There is no way she can drive around to sort this. Today I tried to sort things with Andile on 808 - reference 1- ********** 0506. I was prepared at that stage to change the a cheap voice package. She said that a contract cant be changed without going in store (which my mother cant do for 3 months). I then decided that we would rather cancel the monthly contract and change to pay-as-you-go and she says that i cant do that without a cancellation fee ! How is this possible??? We specifically did not take a device so that would not have to pay a contract. She then said that I AM paying for a device, which we did not receive. She explained that this was the "promotion" fee on the bill. This is just taking advantage of a pensioner... She has been paying for data that she does not get. And she is paying over R400 a month for what ? No device - No 40 gigs ? And now a cancellation fee? All we want now is for the number to be converted to prepaid with immediate effect, and for her to be refunded for the data that she has been paying for since December and not receiving. I am not accepting this at all and want it sorted immediately. Apparently ********** 477 is also under her name. Not sure if it is something she is paying for but we want that cancelled as well. You are welcome to call my mother direct ONLY to clear security but keep in mind that she is just out hospital and cannot be upset by you about this. After clearing security with her you are welcome to then call me direct to take this further. Amanda ********** 882
