VODACOM THE WORST SERVICE PROVIDER EVER.

I have send bad reviews so many times to Vodacom and they dont even bother. My account is in arrears due to incorrect payments made which I got from Vodacom's system. I short paid my account. How on earth is that possible? One of my accounts amount is each and every month R101. for 24 months, suddenly it is R158.00 asking YOUR accounts department why, sorry I dont know. I haven't changed or upgraded. Can you send me a statement from September 2017 so that I can have a look to see where I made the wrong payments and therefor are in arrears now, No I cant sorry am not authorise to send it to you. I would like to cancel some of my numbers which contracts ended, "Sorry you are in arrears we cant cancel" Who wants to do business with Vodacom, after this not a new contract ever with Vodacom.
