Poor Service!!

I am very cross with Multichoice, for the past 2 months ive been trying to downgrade my package with multichoice and when i phone in i was advised to call on the last day of the month, so i was forced to pay the full subscription, so last month i did exactly that and got hold of Kirrin Kgopa, she advised that my package was downgraded, so a day later i received a massage saying that i still have to pay the full subscription yet she confirmed that it was done, and then i phoned in to enquire as to what is happening and only to find out my dstv account was still not downgraded , the guy that i spoke to told me that i went into the self service at “4am” and changed it again which was a lie and as when i tried to explain to him he just placed me on hold. As it is im stuck with 3 tv’s that are not working however i did make the payment for the downgrade package that we had agreed on earlier and now im forced to pay that full subscription AGAIN... i dont get why is it so difficult for multichoice and their stuff to do their job yet they quick to upgrade us without any hustle , somebody better get back to me before close of business today or else im cancelling all my 3 accounts with you guys cause even your self services are as good as useless, nothing really works!!!
