Tech Support Call Wait Times/Slow Speeds

I was about to recommend this service to friends and neighbors as the first week of service was so much better then my 3MB end-of-the-loop Frontier DSL with speeds ranging from 25mb to 70mb. Sad to report though, for the last week it's been off/on (the reason for my tech call) and is fairly unusable. Speeds are wildly all over the place from .02mb to 40mb down (up is fine). The first tech after an hour wait time went over several things, but  ]gave up and put in a ticket to the cell tower group and promised to call back the following day. My 2nd call to tech support, when the first never called back as promised had a wait time of over 2.5 hour and could only tell me there's been no activity on the ticket. This morning speed tests again all over the place, sometimes with no internet at all. I've had to put of cancelling my overpriced $50 3mb Frontier DSL until this can be solved. 😟
