Bad service from Retensions department

I sent a mail to Cell C on 24 Apr 2015, informing them of my intention to not renew my current contract and I want to move to prepaid, the contract expires on 24 May 2015.<br> <br> I received an email on 28 Apr 2015 confirming receipt of the notification which stated that someone from the retensions department will contact me within two days. I received two calls in the two following days from a Cell C number but when I answered it only had call centre music playing in the background, so I hung up.<br> <br> Today, 4 May 2015 I called the department directly. After waiting too long for the Cancellation Department on two occasions I called the Upgrades department to see if their response was better. Sure enough a lady answered and I asked if she could help me with cancellation, if not, she should please put me through to her manager. Her manager duly answered and I asked to be put through to someone that would actually answer the phone. I asked for his name, which he gave as Thabiso if I remember correctly. Then the line went dead. I assume he hung up on me.<br> <br> Please check the voice recording, I dialed 084 143 at 14:49 according to my Cellphone.<br> <br> Please get back to me ASAP regarding this cancellation
