Well I do have the same worst Nokia Customer service here in the Philippines. I gave them my phone because the capacitive touchscreen on my Lumia 620 is defective. It took me 3 months to get my phone from them.

Well anyways, I have moved on and sell that freaking unit and brought a L1020.
The proper way, according to me, even the service center is closing, at least they should still process/repair the phone and then send it to nearby Nokia Care or perhaps send it to the customer's address.
