Vodacom ****mers

Vodacom is ****ming people daylight. I have been battling with Vodacom since September and to this date my issue is not resolved. First they debited me for a contract that i don't have after back and forth they said they will refund me they have issued a credit note, last month they over billed me with R400 I phoned to enquire they couldn't tell me what the R400 was for and they said they will issue another credit note and the consultanted said my December invoice will be paid by the Credit note as Vodacom owes me to my suprise today I get a message that my bank will be debited on the 27 i call ro enquire since they said the December invoice will be paid by credit note they are now sending me from pillar to post. @Vodacom please fix your ish and refund me my money
