Epson India — Regarding bad service at service center

Address:	534102

I am using a epson printer that warranty is completed. I went to service center for it's printing complaint. They said that printer head is not good for printing. So they changed that with new one and charging Rs 4, 000/-. And then they do test print with cheap paper. I am dissatisfied with that. They said that it is good and it need some time to set. I return to office and to do print but printing quality is not good and due to bad service it is getting different noise. For that also it is shaking the printer. Please respond and give some guidance.
