Bad customer service and response

I have never recieved such bad service in my life. I would understand if I was not up to date with my payment but that's not the case. I have submitted POPs to about 100 million people who work in the so called finance department and not one of them have been able to assist. I don't understand why this company is still operational. If you guys know of a better and trusted fibre company please let me know. I want out of this one because they just give me a headache.
