Vodacom Milk it

I have 3 contracts with Vodacom. I could afford it then, then now my financial state has since changed I can no longer afford all 3 contracts. I have called Vodacom a numerous times to explain my case and ask to be released of 1 contract that has to come to it end of term. But no they keep on selling me data minutes and billing me. Before signing a contract with Vodacom please make it a point that you an Attorney or you can afford legal protection because clearly they will milk you for what you have. Need i mention my contract expired in January this year. I regret the day I took their first contract because they don’t sympathy with their client.. to them you are just a number. The next contract will expire in Jan next year and I don’t even wish to know what will happen to me. Vodacom you are cruel to say the least.
