Canon MB5440 printers

I’ve bought 2 Canon MB5440 printers in the last 18 months and each one of them breaks down due to an error. To fix the error is costs more than it does to buy a new one anywhere. I returned the second one to Foto Discount World which trades as Foto Digital World because it was still under warranty. They were supposed to fix it but I’m still waiting to hear back from them 3 months later. There’s no feedback on when my printer will be ready. I keep calling to find out but I get the same response: either “Herman will call you back” or “We’ll find out from Canon and let you know”. No one has anyone called me back out of the +8 times that I’ve called. They keep blaming Canon for the delay and say that they’ll find out when it’ll be ready. Not once have I received feedback. I want my money back or a new printer but they said “No”. Will Canon please step in?
