Pathetic service

I took contract with react alarm for alarm system for our home with Fidelity ADT. My account is now suspended. I have made payment to react alarms in November 2023 , funds are in their bank account. I have sent numerous emails with proof of payment and the lady who is in contact with me is DEBBIE. The only thing she does best is to send me reminders that the account is overdue, when you reply and send proof of payments NO RESPONSE. YOUR service is unacceptable and pathetic , just image you made payment and your account is suspended because the company or whoever is responsible is not doing their part.
