I bought my Nokia 7600 on april of last year. A month later, the sim card got blocked. I called 3s customer service, they asked for all my details and they said my new sim card would be delivered to my home a week later. 2 weeks passed by and i called again. They said they didnt have my details, so i gave them again. I had to call them back 6 other times.

On OCTOBER, after i unlocked my phone, changed networks and gave up about my replacing sim card, 3s sim card arrived.
5 MONTHS AFTER I FIRST CALLED THEM!
