MyTrack have had a problem today, as Olwenh said.
You need to get familiar with the chat system, as this won't be the last problem you have with them!
Whilst the current problems are being aired on the public channel, for any charting problems you have, click channel 7 and they will then respond. Mind you, some of those guy's have got real attitude, so ensure, when they try it on, that you remind them who is the customer - THAT's YOU! They then back down and pretend they didn't realise what they were doing. This has happened on a few occasions with me and I've ssen others subjected to it. I think it's because the chat boys are based in New York (2000 miles from HQ) and NY IS attitude.
