Terrible service

I am stunned from having connection problems when I'm at home to billing someone from Telkom accounts called how do they get this so wrong my account gets paid on time every month and then they have the audacity to say no record is on file of me calling in to complain about connection problems the contract is almost expired and since inception I have raised my concerns with them it was confirmed that where I live connection is a problem they even called and offered me 250 Meg's of data for a couple of months shows just how unaware they were offering stuff for no reason in the meantime I'm still trying to connect when at home worst cellphone provider ever no doubt
