Supersonic - very poor service

I have been with Supersonic less than a month on their LTE package and have had endless issues from the word go...connectivity, slow speed, billing, cancellations, you name it. I'm not sure if the helpdesk knows what they are doing, as it takes them hours to respond and even days to sort out simple queries. I have cancelled my service with them two weeks into the new subscription month and service is very poor and I would not recommend this company to anyone.
