Cancellation of contracts

Hi. I've been calling the cancel department for a while now. Most recently was on the 22nd of May when I spoke to Zakithi who tried convincing me to stay on. She promised me a call back the next day but called at an inconvenient time that I didn't agree with. I've tried looking at other options but I just can't seem to find anything hence my resolve to cancel. Finances are tight too. I've had my contract for a while now but it's time to part ways. I think it's a sign, I usually don't have an issue in finding something but circumstances change too. Vodacom, please cancel my contract on *** & later on, cancel the one on ***.
