I upgraded my contract and the person told me that I'll be paying R139, I receive my invoice and there's an amount of R269 going off on it. I also got charged R417 for my ****le *** which I don't know where it came from because I capped that number to the R99 that was going off. Eish, I want to retract my contract and just cancel that one. 3. The debit order bounced last month on the 26th, I was expecting R971 to go off and R1390 went off on the 28th. Today I get smses saying my account is in arrears of R2522.52. I am very disappointed in telkom honestly, why don't they just say the truth from the beginning? They are charging me R1390 for the bounced debit order
