[Closed] Have you been caught out like this?

This is about being overcharged on my mobile account, not my fault, so got a refund when I saw my bill and called up my mobile provider.. Here's what hapoened:

On New Year's Eve at around 23:15, I sent a group message to 25 of my contacts wishing them a Happy New Year. I was thinking I'd text then, rather than wait until midnight to mitigate the risk of delays in them receiving these messages.

The message came back as failed, so i resent it, not knowing whether it was just one or all of the recipients failing to receive the message. Then it failed again, so I sent it again. And once more - I'd had a few and thought what the hell, I have 300sms/month and hardly ever text. Some people got it, others didn't. I concluded that I left it too late and that the network was overloaded.

Then I got my bill today, with nearly £30 worth of MMS messages outside of my plan! 😕

It transpires that when the network is overloaded, it can sometimes resort to sending SMS as MMS. Well this was what the tele assistant said. Anyway, I got a full refund with absolutely no quibble.

I wonder how many people out there got overcharged like this, not even bothering to check their monthly online statement (by chance, this was the first time I have checked mine in several months - all others were fine luckily).
