Worst service ever

I have been struggling to get my debit order date moved from the 27th of a month to the 1st of a month since the beginning of July 2021. No debit order was collected from my account during Aug, Sept and Oct and I had to constantly call in to find out what was going on. I made manual payments, just to be penalized with R70 every month for a debit order problem that was not my fault. I tried cancelling the debit order at a Cell C store, as I was advised by the call center, only to hear that it may only be done if you have been retrenched. I phoned in again and provided the call center with my new banking details. I need the R70 penalty fee removed from my account and credit amounts left on my older contracts moved to my current one. I phoned a week ago and was told it will be escalated, but I had no response regarding this up and until now. Currently on the phone to the call center, waiting for 20 minutes just to get answered! Will definitely not be renewing my contract with Cell C the way things are going now!
