What is happening

I am a very unhappy vodacom customer, last year October i cancelled my contract and I was told that i needed to pay R686 which i did and i gt a statement in march showing that i do not owe Vodacom. I then received a call saying that Vodacom is cancelling my number. I visited their store and they gave me a diffent story saying that my contract was renewed on the 3rd of June, I did not ask them to do that so I asked who did and they refered me to their client contact centre which did nt help but refered me to their legal department which also transfered me back to the client contact centre. This was October month when they told me i owe R2 241.00 and yesterday 13 November they sent me a message telling me that i owe th R4 267.80. I do not know what is happening but Vodacom must sort thi out.
