Day light *******

I called Vodacom to stop my contract once it came to an end in July and i was told that i have to pay an outstanding fee of plus or minus R700 which i did and i then called them back and they told me that i have to pay another R200 rands since my account was suspended due to not working at at the time in January .I then activated my services again by paying an amount with arrears being included .I then requested my original contract with the network provider to see if the is a condition or term that i might have missed regarding this .The contract has no clause about me paying an extra fee just because i had my account suspended and also seeing that i had to pay arrears for missing payments .The notice period of the contract states that it is only 20 days but the Vodacom consultants told me that i had to serve 30 days .Vodacom is simply trying to rob me and want to keep me in their books and im not happy at all about that
