Telkom- Bad service and pick pocketing funds

From the month of February I have been debited for incorrect amounts as well as at the incorrect dates . I have stipulated that I should be debited on the 5th of every month but I am being debited on the 5th ,15th ,25th and 31st . Due to being debited at the incorrect dates there is no funds in the account and I am being charged rejection fees from Telkom as well as bank charges . I have called Telkom customer care and went in-store numerous times and could not have this issue rectified ,the staff at Telkom where very unhelpful and do not follow through on the promises made . On the 18th of September I went in to the pavilion branch and took through my6 bank statements to have the account corrected they advised that they systems where down and that they would submit my statements to customer care as soon as they where up and running but this was note done .The lady I spoke to in-store was Mandisa. On the 26th September I called call center and spoke to Kabelo Mangwedi at 13:50pm an requested that I speak to his manager to which he told me his manger(Tumisang) was on lunch and would call me back but no one called me back to date .On the 4th November I visited the Westwood Mall store and was advised I will receive a call in 15 minutes - this never happened.Manager passed the blame on to the Billing dept. Disgusted at this customer service .No one takes accountability and Telkom keeps robbing innocent people.
