Useless network and *********** customer service.

Vodacom is giving me the run around when It's coming to cancellation. Their network team advised that he request my contract be cancelled due to persistent network issue. 4 days later I get an sms stating my issue has been closed and thanked me for my continued support. What an absolute joke! 5 days later I still did not receive this phone call to get my contract cancelled. Their media team is basically ignoring my request and saying the issue has been escalated.. I want out of this bad and useless contract. I'm paying for LTE and getting absolute *******. Less than 1.0mb download speed all the time and they expect you to pay and be happy!
