Bad service

This people a very helpless we have been complaining about the amounts that I been charged every month on our bill and they dont want to assist us telling us we must pay and log a complain after. Ever since we lived in this house we have been making payment the actual amount we need to pay monthly is R1300 but we will pay R1400 or R1500 (extra with R200) but their statement will come back saying we owing 6000 + which they including the developers fees that they need to pay and we sent them the meter reading before we moved in but they failing to collect from the developer cause they know they been paid by Cosmopolitan hence they dont want to collect this amount from them. They keep on cutting our electricity for nothing cause all they need to do is collect this money from Cosmo but no cause they all ******* they not. This people a really full of **** they better sort out this before we escalate this further cause they think we dont know people from higher places as well.
