EXTREMELY difficult to cancel a contract with MTN

I have been trying without success for the past week to cancel my contract with MTN. Whenever I phone and select "cancellations" the call goes into a never ending loop with playing the most annoying music without anyone actually answering the phones. I stayed on the line for about 10 minutes then I give up and try again later. Then try again the next day and so this was going on for a week. I then phoned MTN and selected "upgrades" and the phone was answered in two seconds flat! They then transferred me back to "cancellations" and low and behold I was back in the loop. I went to my nearest store and they said they cannot process cancellations I have to phone the number I have been phoning for a week. I finally decided to select the "*****" option on MTN, the call was answered relatively quick and I asked the consultant if I could report MTN for ***** as they are not assisting me in cancelling my contract which could result in the contract running for another month. I was then put through to a consultant that assisted me, but the process was dragged out with "the system is slow" or has "kicked the the consultant out" and then had to start again. When I asked the consultant to repeat back to me in order to confirm my contract has been put on pay as you go in order for me to transfer my number to Vodacom, the call was dropped and no one phoned back. I am now back in the same loop trying to find out if my contract was successfully cancelled. MTN has insured that for my remaining life span which I estimate is about 45 years which equates to about 22 contracts, I will not ever support them again or recommend them to anyone. I will use a payphone before taking out a contract with MTN ever again.
