I just got a LaptopConnect card from Cingular (the new at&t). I called their offices to activate it. Instead of activating the SIM card for Option GT Max 3.6, they replaced my mobile phone’s SIM card.
Then they told me that the old SIM card is now deactivated. It would soon stop working.
And then it did, so I couldn’t even talk to them.
Cingular customer service, like that of most other companies, is terrible.
