UNHAPPY AND FRUSTRATED VODACOM CUSTOMER

I was using Prepaid from Vodacom before someone from Elite Mobile called me and offered me a contract with Vodacom. The contract started around August 2014, I was unaware that I've got a contract with Vodacom till I went to the bank to get a statement. The statement showed that every month Vodacom was deducting money from my account. I Stopped paying and voice machine kept calling me telling me to pay the money. I continued not paying. Now Vodacom has deleted my number. Every time someone calls me it says the number is incorrect. I went to Vodacom to find out what is happening. They told me to fix this problem I need to pay back money that my account is in arrears with. I paid the money. After paying they told me I need to pay another money to activate my sim again and also they say I must pay money to cancel the contract. Now I am not using my Vodacom number and they say month end I am suppose to pay money for being in contract with them even though they have deleted my number. Someone Please help me. I need my cell number back I am missing out on important calls. Thank you.
