Upgrade gone wrong

<p>My issues with Vodacom never seem to stop,</p> <p> </p> <p>I was called around the March by Vodacom, to advise that my contract was due for an upgrade, so i went to the store to get this wonderful offer and was very happy until the end of April when i went to pay my account and was told i was owing funds for the old contract and the new contract, and correct me if i am wrong but why in gods name will i upgrade my contract if, i have to be paying for two contracts??? i would rather wait 2 more months till my contracted ended and just signed a new one with Vodacom or changed to a Different provider. I have been with Vodacom since i was 16, and the service i have received is appalling, my line has been restricted twice now and every time i call i must explain my self and only to be told that Department can not help me and they will put me through to another department. i have logged a Dispute with Vodacom, only to be told that they closed the Dispute but no one informed what the out is. PLEASE HELP ME</p> <p> </p> <p>I was called by a very nice lady who advised that they will credit the account as i was incorrectly advised, however i see my line been restrieted again? when i can the call centre they tell me im still in arrears??? for what now??? they cant even explain to me why? </p> <p> </p> <p>I am been told that i have to pay for the new contract for March, April, May however my contracty will only end in June 2018, how is that possible, please can someone confirm that my original contract has been cancelled and my payments i made is correct. Can someone who knows what they are doing call me and sort this out once and for all. PLEASE </p>
