Protect America, Damon, Billing Manager Refused to credit me for monitoring charges on non-operating equipment Austin Texas

My alarm box went off line due to a PGE problem on March 31, 2016. I contacted Protect America the next day, April 1, and told them that I was canceling my service due to the fact that Protect America didn't inform me that my box was non-operable. I sent probably 10 emails in regard to this, but PA kept insisting that I still owed them a monitoring charge of $29.95 for the month of April. I was later contacted by a manager there who told me that due the matter was closed, and that I wouldn't be responsible for any further billing from PA. So, when I got a statement indicating that I still owed $29.95 for the month of April, I was extremely irate. I just spoke with Damon, the billing manager ( who should lose his job for providing such poor service on accounts) who has now told me that if I failed to pay the $29.95 fee for April, my account would be sent in for collection at the end of the month.

I have paid every dime for monitoring of my alarm box since getting it close to 10 years ago. Even though my house was brokene into dozens of times while I had a monitored alarm, I still kept payments current. I am a disabled woman who is living on a very small amount of money, and the amount and type of harassment I have received at the hands of Protect America constitutes extreme harassment, especially since I was told verbally that I wouldn't be responsible for any further payment to PA. I told Damon that I would be happy to file a harassment suit against them for trying to bill me for services that were not being rendered on equipment that was non-operable. I should also mention that no one at PA attempted to trouble shoot my system to see if they could get it back online.
Long story short, the smartest thing PA should do is simply credit the $29.95 for April, when my equipment stopped working. That would be the prudent thing to do rather than causing me to file suit against them for harassment, which I plan to do if this is not resolved to my satisfaction. I am now requesting, again, that I be credited for the $29.95 PA is still attempting to get from me through the extortion of damaging my credit if I don't pay for something that was nonfunctioning and not being monitored, which is what I was being billed for.

My account was paid for by automatic deductions through my bank account at Chase Bank.  It was always honored, until this incident occurred at which time I had the bank stop payment for any charges requested by Protect America.
