Pathetic after sales service

On Thursday my "LOS" (loss of signal) light went on and despite 7 phone calls and 5 queries listed on the site, I am still without internet. Open serve was supposed to resolve and I just get send into circles. I'm isolating and have to work but the service received is absolutely pathetic. My son is on Gr 12 and also has no access to his school work. Worse decision of my life
