Cancellation

Vodacom is a bunch of ****** cancelled my contract last year since i cancelled it early had to pay a cancellation fee which they gave me the quote and I was supposed to fill in a form and send it back to to them I paid the fee and sent through the form its been over a year now and they decided to debit me for what reason I don"t know I have called them over 5 times all saying one thing your inquired will be solved and you will be refunded but instead my bill keeps increasing I am really tired of them honestly if you looking for a cellphone contract don't get it from Vodacom
