PATHETIC CUSTOMER SERVICE!!!!!

I had a wi-fi problem that needed a technician, then a technician came a week after my wi-fi was down and he said email all the relevant people that a callout fee was not supposed to be charged because he saw where the fault was!… After several visits to the office they I got a call that my account was credited they agreed!… and I have been getting SMS threatening me that my services will be suspended they did yesterday… My cut off date for paying is always the 6th of every month since my date is the 1st, when they suspended me yesterday I called them they said I still owe them the callout fee, and the Queenstown office says the only payment i’m suppose to make is the R499 for february and they called each other and I made the payment for R499 because I was given a go ahead!.. they told me the call out fee case is up again, now my question is, if we don’t call them when we having problem are we suppose to be their technicians and fix the problem?… besides that I always have network problems!
