Upgrade

I upgraded my phone contract with Vodacom. The salesman did not explain everything to me. I signed a contract thinking I'll be paying less than what I was paying before. When I went to report this, the manager promised to call me the following day as the the salesman was off duty. He never called but the salesman called and he apologised. I told him I wasn't happy. He then said he'll call after 30 minutes but he didn't. I called the manager the following day and he said he can't help me as I signed all the documents and the salesman said he explained everything.
