Vodacom is aweful!

Vodacom, You level of customer service has been appalling and I am not impressed with the sheer inability to resolve issues in a timely manner. I was sent an invoice for my new contract and charged 500+ rand for 10Gigs if complimentary data that customers receive when starting a new contract or upgrading. After alerting a consultant of yours, I was promised a call and resolution and it’s been days later with no feedback and unanswered emails. I am left to believe that I now have to pay for COMPLIMENTARY DATA! This is UNACCEPTABLE. Also, it stated that I would receive a educational voucher to the value of R10000 and receive NOTHING. I also had to call in to remind the consultant to load my 1 gig data that was promised to me when signing my contract. This is disgusting. I refuse to pay for something that is complimentary and also not communicated to me.
