Customer Suffering due to Telkom Human Error

I opened my cellphone contract with Telkom in November 2015. From the approval stage to now I am still having problems with Telkom. Telkom captured my incorrect banking details even though everything was provided from my bank statement. My account was debited for the first time on the 24th March 2016 when we figured out the end of January that the banking details were incorrect. My account was suspended each & every month since Nov because of this & I have had to do EFT payments. Now my account was handed over to Collections & I have to wait 14 days for a debit order to clear because of Telkoms incompetency. Had my details been correct the first time around, I would not have been in this situation to begin with. I do not see why I have to suffer without having my account active due to Telkom not double checking their capturing of a clients details. I have spoken to many consultants already & was now told that my account will only be activating by the 12th April 2016. I was told by Dumisa that he cannot open a case because my debit order has not cleared yet. IF PEOPLE DO THE JOBS CORRECTLY THE FIRST TIME, THINGS LIKE THIS WON'T HAPPEN!!!! This is unacceptable.
