Day 2 internet issues

I've had issues with the wifi since day one in march.. Its gotten much worse with daily outages for varying times. Its been extrememyl frustrating because I work at home via internet. I felt TM was very dishonest in saying I qualified for a free phone, and indeed, I'm credited with a monthly payment. But, I'll have to pay off a phone i really didn't want in the first place in order to get out of this awful Tm wifi service. 

Also, I did finally replace the modem after spending hours on the phone with tech; now its even slower and just as many events of no service.
