Bad service

I have been with Vodacom for more than 20 years. I speak Afrikaans so English I know but not really my strong point. A lady called me and told me that two of my contracts are up for renewal and she got me a better deal. She talked so much and so fast I could hardly keep up. Now all of a sudden is my data contract 400 gig changed to a 100 gig and the premium is more that double. I called vodacom customer care and was told that it will be fixed and a consultant will call me. I am still waiting and waiting its been nearly a week now. So please rethink before you take out a contract with this company.
