I am besides myself with frustration

I wish I could give zero stars. To start, my router arrived only after 6 business days, even for this I had to spend a couple of hours on the phone. And then this morning my connection light was red. Phones support and I was assured this was a normal one time occurrence. I was told to switch my router off for an hour and turn it back on and everything would be fine. After that hour the light was still red and no connection was in sight. Spent another hour + on the phone with support and after going back and forth and trying the same things over and over again it was concluded that something was wrong with my sim card (keep in mind this sim card is brand new). I was told to speak to customer service who would be able to check my sim card for faults. Waited an age to speak to customer support, answered a string of questions only to be told that she has logged a case with her manager and I could expect a response in about 48 hours!!!!! WHAT????? I work from home like a lot of people and this is influencing my work in a terrible way and I'm racking up ridiculous mobile data costs to remain online and working. I find Supersonic to be incapable of solving real problems in the fashion it should be done, the advisers throwing me with their red tape and BS. I also find it offensive that they consider their time more valuable that mine. Think I should send them an invoice for the time I spent chasing after answers because they were not able to provide any help whatsoever.
