Worst Company to ever have a contract with.

Both myself and my wife have had Nashua Mobile contracts touching to 6 years. We haven't had a days trouble when they were the authorizing company. Now we are with Altech, for a full period of 4 months, and it has been one big terrible nightmare since we migrated. Now all of the sudden there is a price increase that was made, without prior notice. There is a constant accounting problem on my phone, which keeps getting soft locked. My wife's data runs out like water. I want to cancel my contract, but they refuse to come to an agreement with me. I am left with no other choice other than going to the CPA.
