Vodacom bad service!!

Have been a client with Vodacom for more than 20 years - struggling to cancel contract with them as I have not had internet for two weeks now and at the end of the month they just want to be paid. Vodacom making me jump through hoops to actually cancel my contracts with them - they don’t answer the phones, they making empty promises of solving issues when my request is simple to just cancel my contracts. If they don’t respond to this then I will take them to ombudsman as I feel they do this on purpose to make clients despondent and then not cancel their contracts.!!!
