Bad service

I am not happy with the abuse and treats that i am receiving from telkom. My account is up to date yet i am being told that I owe, yes I do agree that my account was outstanding but that was rectified, on the 11 of January I paid the amount of R600, I am told that the amount will take 7 to 14 days to reflect, the R600 must be credited in to my account because now telkom owes me because on the 15th they debited the full amount, which I am also told that it will take 7 to 14 days to reflect. I am receiving calls from collections forcing to make payments or I will be blacklisted, how do you blacklist me while I don't owe. My account is also still suspended as nothing can be done until after 14 days. Now I am receiving sms while Telkom is not updating their records. This is *********** and lack of customer service. Your service consultants are unprofessional and have poor listening skills. Please pay me back my refund on R600 and update my records.
