[Resolved]  Nokia - 2630 — Bad Service from Nokia Care Malleswaram

I had purchased a set of Nokia, Model :2630 in January this year.I had given my handset to the nokia customer care which is
Address:Brightcaree, #51/1, Srikantha Mahal, 1st floor, 1st cross, Sampige road, Malleswaram, Bangalore-560003 on 10th September 2008. Job Sheet No.:[protected]/080910/75.
Problem was first i had a Faulty Display, they took the set for repair and said would return the same by 13th September 2008. Then they told the set could not be repaired by them and that they had send it to the higher level for repair. They had told me to wait for 10-15 days and get back to them. When i did the same i got another date as 4th October 2008. That day also i didn't get my set and because i was upset and argued with them they gave me a backup set for my use. The next date which i got was on 16th October 2008. When i visited them they gave me the set without checking it completely.I found another problem that the keypad was not working properly.I shouted on them gave back my cell to them once again for repair, i got another date. In the mean while i called up the Nokia Cust. Care and registered a complaint and Escalated the issue. The Complaint number : 2-3ECZ9N. They had asked me to collect the cell on 22nd October 2008. I didn't get the set. On 23rd October 2008 i got my replaced set.
Is this the way you people work and care about your customers? When ever i had called them, except they giving my cell back i was getting dates.. stating that i would get it on that date. They don't recognize the problems themselves before they deliver the repaired set. We should do that work, alert them in every stage of their work. What for are they working? If they don't know how to work in a disciplined manner?
I need to know, as a customer of Nokia ; what course of action has been taken against them.
