Disheartened customer

I've having network problems with these guys well almost the whole yeah the consultants always say they are escalating when they finally resolved my problem by installing an outside router which I waited for 2 months to be done I requested a sim swap the wrong sim was delivered and my router is deactivated and that was three weeks ago im sitting with no network and im paying I've been calling everyday to request a technician to come sort out the matter and they have been escalating everyday for three weeks I even went to the walk in store in queenswood they promised a technician will be in touch within 48hours it been a week now this service provider is horrible they don't give a damn about their customers but they will send you a million reminders when it's time to pay their bill I have had network for three weeks and already they sent an email to remind me to pay what in the world am I paying for exactly
