Cancelling My Contract and Converting to Prepaid

I cannot cancel my contract with you guys because you are all on strike and your slow a** service sucks badly. I have been with you guys all my life as a customer and I am disgusted with you. <br> <br> I called in the beginning of May 2015 to have my contract cancelled because the 24 months was finished. I was told to call back on the 19th of May 2015. I called back (Ref ***) and I put through a cancellation request there is no direct line to speak to the cancellation department as well which is F***** bullsh*t. <br> <br> I called back multiple times and switched my phone off as requested but still nothing OH!! let me not forget every time you call you have to wait 30min - 60min before someone answers. I called back on the 2nd of June 2015 (Ref ***) and put through another cancellation request and it still has not been cancelled. <br> <br> You p o e s laaities took my money at the end of May and my phone is paid up so why are you still charging me the same fee (i.e. only charge me for the airtime). All I require is to move to prepaid. Please can someone sort this damn issue out for me.<br> <br> Let me also not forget when I want to take out a contract your'll are ready to take my MONEY!! But to cancel
