TELKOM MOBILE IS A ****

I did an upgrade 2 moths ago ,last month my bill was R1416.43 instead of R286 i queried the invoice before the debit order went through ,I spoke to a lady Zoliswa Kweyi and she said my contract is on "spend limit" meaning its not a top up that's why my bill is so high .I told her i have never signed up for that and the guy who did my upgrade didn't mention any of that ,she suggested i request a recording ,since i did my upgrade over the phone .Phoned their sales department was told the details of the person who did my upgrade are not showing on their system ,escalated the matter with their manager Fortune Bhele ,who never came back to me ,sent several emails to Zoliswa she didn't respond .A debit order went through on the 26th of October 2021 ,instead of R286 they debited R1416.43, money i dont have which was supposed to be for my daughter's fees .On the 3rd November 2021 i called again trying to understand what is that money for and why i can't get a recording ,spoke to Nomusa Bhele and Aubrey they couldnt help .Called the cancellation department spoke to Nicolette Pholoba she said i need to pay a cancellation fee of R2000 and tried to resolve the matter ,i asked her to cancel and close all the benefit and this sim card is used by an old and she kept on saying the old lady was aware that is making calls and me fighting wont help and i wont be refunded (mind you the benefits of the previous contract was she could phone telkom number with 3000 minutes ) How is the old lady uppose to know that now she can't phone with free minutes were as we were told the benefits will be the same as the previous one ,but they will also add all networks free minutes .This morning 4th November 2021 i received another invoice saying i will be paying R1015.26 instead of R286 ,i again called and spoke to Ntokozo Cele who said i was charged for making calls and yet i on the 21 October 2021 i requested tht they change it to top-up .Im so fustrated and angry ,my mom i using the sim card ,there is no way she can spend so much on calls ,she uses her telkom free minutes to phone telkom numbers .I want my money back and cancel all my contract with you and I won't be paying a cancellation fee because you are the reason I'm cancelling and your sales department was misleading ,you busy ******** people ,I also want to cancel my DLS WI-FI contract .
