Bad Customer Service

I've signed up online contact phone with them 2months ago through telephone, I've agreed with them to Pay R250,00 they've never sent me any documents indicating my terms of contract.after that I've found out that I have been charged for pro-rata which was never highlited to me and also my premium was changed R294 which was not agreed upon.I have been trying to contact them in all their platforms with no joy,they blocked my Data and handed me over to their legal department despite still paying my agreed payment R250.I regret my decision as I had similar issues with them long time ago, I thought their service has improved clearly not I won't recommend anybody to deal with them.Their customer service center is.even way terrible.
