Unfair client management and billing

I have a contract with canon for renting a printer, and I never experienced any problem with their billing until the company was sold to daisympu. Since I have been receiving extra monthly bills that were never discussed with me when canon sold the company to daisympu. I have enquired about it from both canon and daisympu, but i have never received a clear response until this day. This started last year December, but how ever insteading of fixing my quiery I have been enticed into upgrading my contract ( to another 5 year contact) thus reducing my monthly rental bill. Now the printer is printing the paper grey making the documents to look ugly we are unable to see what has been printed. When the issue or error is reported we are being informed that it wont be fixed until the we pay bill ( the extra bill from daisympu is charging us monthly).

I am extremely unhappy about the service! and waiting until my contract ends (2019) is an absolutely one hell of a long time!
