Worst service ever

Worst service ever payed my bill on 26 April, line disconnected 5 May, trying to get the line active is a bigger mission then anything else, no Manager steps in most of the call center staff clueless, legal makes me drive to East Gate that I must sort out the payment myself even though I emailed them the proof of payment 4 times, still nothing and still no feedback, even emailed the proof to a manager still no response, what more must n customer do, who is paying for the loss of income in convince and time I have to drive up an down because they have no clue what they doing and there own time to try and resolve this, but the best is I can't even phone legal from my cellphone as they have blocked my cell nr from phoning them
