Vodacom bad client service

Good day Vodacom and ICASA

I would like to log a formal complaint against Vodacom. I spoke to an agent ( Kilo) yesterday regarding an upgrade for ***. The reason why I am upset is because they make false promises. It happened two years ago as well and I gave Vodacom another chance, this time I am finished with Vodacom!!!!!!!! She told me that the package includes monthly data but in the meantime it was not true, it was only a once off and not on a monthly basis as she told me. I also asked her specifically if the data deal was on a monthly basis and she promised me that it was monthly. I will hopefully manage to cancel my contracts with Vodacom and get them out of my life for ever once and for all. Please advise me how to get this complaint escalated to Vodacom, it will be much appreciated. I am really sick and tired of Vodacom, why do they always lie? It is extremely unprofessional

My details are as follow:

Vodacom account number: N***-5
