Telkom bad service

I was on Telkom selfservice requested the agent to change my banking details to my new fnb savings account and they loaded the account as a Cheque account. After being calling them more than once i paid my account at checkers the payment reflected the next day i was forced to take off from work to sort out my account and now i have been cut off after the payment has been made. They tell me that my account will only be reconnected with 5 to 24 hours due to their mistake this in unacceptable i paid for service and my banking details are still the Cheque account and not the savings account. Very unhappy with this service and treatment of a paying customer
