Very Poor Customer experience

I was blatantly misled by the Client Servicing consultant about my outstanding balance on my account which resulted from the incorrect billing on my account. I called multi choice on more than +- 10 occasions, since from April 2019 and i was told that that my query was escalated yet continued to deduct the very same incorrect amounts. only when i reversed the money that they called and told me that they can make an arrangements to collect the very same amounts without addressing the operational errors which occurred from their side. now they have deactivate their services and my case is still not resolved and reflecting negatively on my credit score. ***
