Poor customer service and contious non response on issues

Good Day

I have tried to contact a Vodacom help desk and info but no reply. I have been to your Carnival Mall branch on various occasions ans still no satisfaction.

Please can someone help me. First, why did my contract amount increase as I see without any notification etc. My Number is ***. J J Bothma My new contact number is ***

I need to know when my contract expires as I still feel that the person who did my upgrade did not give me the correct info and after visiting your store at Carnival Mall various times nothing was done to rectify the situation. I am not happy with this contract and the non caring attitude from Vodacom.

When can I cancel my contract?

PLEASE help me.
