Very angry client who wants to cancel

This company is the worst ive ever dealt with, the stuff no nothing and keep transferring me to other departments because they are also confused, and again they have been deducting money i never agreed to, and when i ask who authorized this, they don't know, yet they sitted in front of a pc. They are so unprofessional and literally know know i tell you. But i believe i was just **** to from the beginning about this company. What's worse for me is, a netstar fitter is renting at my workplace but they also can not assist in anything. I asked one of the guys to take out their device coz im really ****ed with the service. Well, they refused also. The stuff at netstar are nor reliable and they like the blame game. It is now towards month end, they will deduct money again without my consent. Get someone to call me and cancel this **** company. I advise no one to ever consider this company.
