VODACOM CANCELLATIONS LINE IS USELESS

Its absolutely ridiculous that I've been spending weeks and weeks attempting to get hold of vodacom cancellations and getting put on hold . Ive been dealing with a very helpful branch manager from Cellucity who has unfortunately told me that only the *** number can be used for cancellations. I find this frustrating as I would like to cancel a data contract and require other info but how is one to do that if you get put on hold all the time even when you call at the open of business ?? its unacceptable that they are so quik to spam you to get your business but the customer service thereafter is PUTRID !!!!!!
