Bad service

Since last year been trying to call about my meter problem but the last time I spoke to two different consultant's they were very rude and didn't entertain my issues The meter is depleting electricity at a ridiculous pace and chows even when switched off My geyser has been off from last year but meter works as if it's on And the tariffs change nilly willy yesterday we bought three vouchers from Checkers at the very same time one voucher gave 24kwwhile the other two gave 22kw but the company does not bother to attend to its customers such bad customer service We need something to be done this is out of hand
