vodacom sucks

I opened an account in two years back with Vodacom a contract of 2 year ,then the contract was suppose to be finish in February this year.i noticed that Vodacom is still demanding money from me of which I find it very strange because the period of a contract is over.so now Vodacom sent me an e-mail stating that I have been handed over to legal<br> I have visited Vodacom branches but they cant resolve this <br> I have never used the contract SIM card so im surprised why they keep on charging me every month <br> I thought Vodacom is the best Network service provider I guess i was wrong all they care about its money not their clients.<br>
