Cancelation ****s

I tried canceling 2 of contracts during the year last year and I was told and offered a better deal. Unknowingly that this contract would actually become locked contract for 2 years instead of month to month. I then tried to cancel my 1 contract as I upgraded the 1 number which would be the same amount of both contracts. As in this time and age we can't afford extra billing. When I went through to cancelations I was then advised on the above. The lady assured me that she will send the request to escalations and they would take 2 to 7 hours for a response. I left it cause eit was the Friday and then all these holidays but it's now after 5 and that turn around time is long over. I. Would like a resolution to my problem and also like that vodacom cancelations. Not lock ppl. On new contracts but rather sign them up to month to. Month contracts as there is a reason we call to cancel our contracts.
