Client say's: "Service!?" Telkom mobile say's: "Huh, what's that!!?"

Months of problems regarding changing my debit order from the 1st to the 5th to the 15 - I have complained several times on Hello Peter - they supposedly reply...then I get an sms to say the case has bee resolved...oh but I never heard a word from anyone...the case is not resolved...

Now my cell phone has been blocked due to a past due amount - but the amount is only meant to go off on the 15th - today is the 13 - what past due amount are you talking about. I have been phoning in for two weeks to query why I am getting this threatening sms.

Wow, what to do Telkom Mobile?
