ADT Fidelity ******* cost recovery from Customers

I received my monthly invoice and found that my monthly fee was increased without any approved and/or communication. Cost recovery for cameras that ADT/Fidelity installed is now being passed onto customers. I was then sent an increase letter based on this new amount. I have contacted the accounts department via mail and telephone no less than 5 times without any resolve. The only communication I received was a forwarded email that it has been escalated. It has now been 3 days since my last follow up. No reply, no follow up, no concern! *** and hpcamanager.jhb.za&fidelity-services.com.
