Nedbank makes it impossible to use their service

On the 12th October I called Nedbank credit cards department to stop my card. This was due to a Microsoft transaction that I wanted to stop due to not receiving confirmation from Microsoft that the free trail was cancelled. I spend 1 hour on the phone and spoke to 5 different people to no avail. All of this happened while hospitalized with Covid. The next day the transaction went through. I finally spoke to Siyajabula who raised a complaint *** . I have since disputed the transaction and had email communication with 5 different people: Margaret Mzila, Sandra Ligege, Thandeka Ndaba,Mandla Thabede and Jonathan Le Grange. I've emailed all of them dispute forms and proof that I attempted t cancel the transaction. I also don't have a new card yet. I spend 1 hour waiting in the Gardens Centre branch 2 weeks ago only to be told I have to wait for an sms which I ever received. The manager said she'll look into it and call me back, however she never called. Yesterday the Nedbank ATM swallowed by Absa card and now I'm left with no way of making transactions or access cash. Nedbank do you realize I can't use your service if you can't sort out a new card. Nedbank please let me know who is responsible for the dispute. Does not seem very productive to have to communicate to 5 different people.
