At least it was only $373.52.
Out first bill with Cingular was going to be around $220, and then every month thereafter around $110 or $115 for 3 phones. 2 of the phones had 1000 text messages (in and out combined). The first billing period though was only 3 days from when we signed up to when that period was over, which they never told us either, so it would have been $220 for 3 days. But anyways, when we get the first bill, it was way over $700. We basically fell out of our chairs, and then saw that some number was constantly sending my phone text messages. I was not receiving them though. I have a smarthphone and 1Gb mmc card in it where all the texts once received are stored there. I think I would remember if I had somewhere around 5800 text messages in 3 days.
We had to call up and explain to them that there is no way in hell any phone can receive 5800 messages in a span of 3 days. That would mean 80 an hour 24 hours a day for 3 days straight. And I only had received 1 "welcome to cingular" spam message.
After we got that "resolved", it kept happening. 5 digit counts of text messages. One month in the 70k's. So we told them to block my phone from receiving text messages. Well it sure worked on my end, because I wasnt able to send any. But that same month, the charges were still there.
It wouldnt go away. Damn cingular. They finally fixed it, about 7 months later, but it still haunts me late at night!
