Customer Service for billing is a joke

just now New Poor customer service experience. I made rental payment, first half is in the account, the second half is in the ether apparently. I make another half payment cause now I'm sitting with no power...that payment is in the ether too. But do you think anyone can help me? Nooooooo. I sent an email a few days ago, 3 days after making the second payment, but thats bad for me cause I sent it over a weekend and they don't deal with billing over the phone...so I am expected to sit and wait, with no power and R15k floating around somewhere...cause they can't deal with me over the phone and I must wait for the response on an email. A ****ing joke. Not only that, but when I phoned, I got treated as if I am the one whose stupid and in the wrong for wanting to get my rental payment sorted, power on and the remainder returned to me!
