Complaint Review: Kilowatt Financial

I bought my home in 2016 here in Arizona, and it came with a solar lease attached to it. Since I bought my home the original company filed bankruptcy and sold to another company. I never had a problem with my billing until Kilowatt Financial took over my contract. They took it over in April and in the beginning I had no problems. In September they debited my account on the 6th of the month, and it is not supposed to be debited until the 15th of every month. Well then on the 22nd of the month, they once again debited my account. 

Unfortuantely my lease says I have to be signed up with auto debit. I tried to call, but of course they are 2 hours ahead of Arizona time so by the time I get home and am able to call they are closed. So I sent them an email on the 23rd of September, with no response, or refund. Well here we are on the 6th of October and guess what, they debited my account again. I have once again emailed them and dont expect a response. I am a single parent on a single income and am really frustrated. If anyone has any suggestions I would greatly appreciate it.
