LCEC Lee County Electrical Cooperative Incorrect billing from them one month before i was able to get my deposit back. Put me 3 months behind Ft Myers Florida

I receved E-bills that go to my bank and the bill is automaticly paid by the "Bill Pay" service my bank provides. One month I recive a bill for $15. When LCEC was called and questioned on the bill they said it was " probably a meter adjustmet". Since this has happened in the past with another elctric company i did not think much of it. Then the next bill arrives and its for over $650, two months of service. When called they agreed to accept the monthly payment and to pay off the rest of the bill in $70 increments every month. Satisfied with this I paid the bill. Two weeks later I recive a shut off notice, when questioned about this the representitive said that we had "stopped payment" on that months bill. My bank verified that that was a lie. LCEC had screwed up the billing again. After phone call after phone call, talking with Supervisiors, etc, they refused to work with us with any solution. Without their help I was able to catch up to what was over $1,000 in payments and am current. Today I received a check in the mail for the amount of this months payment stating I am on a "cash only" account. This entriee mess was due to their mistake, My banks bill pay paid that bill every month fore yaers with not one payment being late. I find it suspicous that the month before I can get my deposit back all of this happens. I have been told by some other people that they had gone through similar circumstances right before they were to get there deposit back. I think they are scammers that just dnt want to give back your money. I have never had an issue like this, only with these people.
