Unhappy Nashua customer

I can not complain about after service because there is no after service at all. I have a printer that stood for 2 years before they even bother to fix. The printer is giving problems again and i am waiting for 2 weeks now. The manager was suppose to phone me and still waiting. They dont honour their side of the contract but i must do my payment every month. I want to cancel my contract but they say i cant. This is the worst company to do business with. In 3 years my printer haven't been serviced once. I am stuck and need to print some documents and are forced to buy a new printer. PLEASE DONT DO BUSINEES WITH NASHUA EAST RAND. THEY ARE A JOKE.
