My contracts still not cancelled after 9 months!!!!

Good day I am at the point of going to my lawyer with this problem. on 26 January 2018, I cancelled four contracts and even got a reference number for the cancellations. In March I realised the contracts were not cancelled. I have put a post on hello Peter and soon I got a reply back from Randall that my problem has been solved. Well it is till not solved as Vodacom still deducts money for three contracts from my bank account. When I try to phone, it is impossible to get through and one has to keep hanging on hoping someone will answer. When you go to their web page, you only get FA&Q and that does not help me at all. One can not even write an email to Vodacom anymore. When I request a call back, it is only for general inquiries. It is so quick to take out a contract, but to cancel one and get answers on queries and problems, then help is far away. That is why I am back at Hello Peter. What can I do to contact Vodacom to cancel these numbers and get a refund for money they owe to me? Something else I noticed is that my contract end dates keep on changing. It even happens with the numbers that I have cancelled. When I cancelled the contracts, it was already their end date, but all of a sudden they have changed to dates next year. My next step is to go to a lawyer and to one of the Consumer services of our local newspapers. Thank you
