Query: there customer service stinks

I had a problem with my roomba after only two days. I wasn't really too worried about it because it was remanufactured so I thought I might have a problem. I contacted irobot customer service. They diagnosed the problem and told me they would send me out a replacement roomba. After a week went by and no one contacted me with any shipping information I went back to the customer service site to complain. Thy had closed my service ticket. I asked for someone to update the status and this went on for more than a week with no response from them. When I asked them to do something to male this experience a little more palatable for me they wouldn't upgrade the shipping of the replacemnet roomba. The roomba may be great I have no idea but the company behind it doesn't take care of it's customers. I would not recommend purchasing a roomba for that reason.
