Telkom worse service Provider ever

My account was paid on the 22 January 2016, Today I see a debit order in my account of the same amount, call Telkom customer service 180 to ask why they debited my account, as usual they do not have an answer for me.I regret having a contract phone with this company since day one I have been battling with them regarding my account , In December it took 3 weeks for a debit order to appear on my statement and they kept telling me my account is in arrears even after I provided proof of payment. I have requested my bank to reverse they debit order twice now, and this is affecting my credit rating. The customer service personnel couldn't even direct me or advise how to fix this permanently, the response I got from her, ASK YOUR BANK TO REVERSE IT.<br> I want Telkom to stop debiting my account, If this not sorted I'm going to the ombudsman. I cant even block them they keep on changing referencing numbers.
