Cancellations nightmare

Called to cancel my contract as I do not need a contract anymore, just a pay-as-you-go. Got talked into the R100 pm option. Straight after the call I realised I cannot afford the R100 pm. I phoned back immediately. They assured me the reversal will be done, I just need to wait for an sms, should take a few days. Week later, phone to cancel. No sorry, you have to wait 30 days about. I am not in the country in 30 days time, so unable to phone the *** number to do the cancelkation then. Any other way to cancel...nope. The biggest cellphone provider in SA apparently doesn't have e-mail. Are you actually kidding me?? Worst service ever and completely out of touch with their customers.
