Query: Poor customer service

I bought a 6131 for my Wife, which she came to like after 2 months of use. Nokia's web site said that I should upgrade the operating software to improve certain features. This worked great on my N73, so went to do the same on the 6131. Part way through the upgrade process the computer lost touch with the phone, and from that point on the phone was dead. I returned the phone to Nokia who have now had the phone two months of the four that I have owned it, and I cannot get any responses out of customer service/repair about its expected return to me. Just hope you never have to use Nokia customer support.
