worst service on Earth

My service has been terminated apparently for an outstanding bill. which is bull because my acc is up to date and i have submitted proof of payment to prove my acc is acc. apparently i have a dishonounered debit order for dec, which is funny because my acc is a cash acc i do not have a debit attached to this phone acc so can this ****** from telkom tell me where they got this 1400 i apparently owe? This is not the 1st time Telkom has done this to me, i really have no choice but to terminate my acc its been 5 days since i launched my complaint and i still have no response, call centre people are typical lazy and rude individuals who provide no assistance. im running a business but they dont seem to care, they suspend your acc for reasons they themselves dont even understand or can explain themselves
