MTN keep you holding if you select the cancel option but if you select upgrade the agents are immediately available.

I have been trying to cancel my contract with MTN, I went into a MTN centre and they advised unable to assist with cancellation. I then called MTN on 135 and selected the option to cancel I held on for over 5 minutes then cut the call. I called back, this time selected the upgrade option within 10 seconds an agent was available to assist. When hearing that I wanted to cancel the agent rudely transferred me to an endless wait and I had to hang up.

MTN I have tried every avenue to contact you, my contract is legally ready to be cancelled please call me.
