As Glastonbury 2013 has sold out in just 1 hour and 40 minutes, those who couldn't get through have been left disappointed.

The frustration is clear to see on Twitter, as many are complaining about not being able to get through to the booking site and phonelines.

The 2010 festival sold out in 24 hours, and 2011's festival sold out in just over four hours.

We're heard some complaints that callers may be charged just for reaching the engaged tone, and with many hitting redial repeatedly, be careful, this could be expensive. The note on Glastonbury's small print reads:

Please note some network providers will charge for an engaged tone

Emily Eavis (Glastonbury founder Michael Eavis' daughter) promised a smoother run of things on the site this year, but wouldn't reveal just how many people had registered:

"The reason I don’t want to give figures is we don’t want to panic people. There were a lot of registrations but that doesn’t mean that there’s going to be all those people trying. I think it’s really important to feel like everyone’s got the same chance and it’s all going to be over as quickly as possible, hopefully, and hopefully it’s going to work really well. We’ve got high hopes this year with the new system."

There were approximately 140,00 tickets sold for last year's musical gathering, but registration closed last weekend - you'll be able to register again for the next round of tickets from tomorrow.

If you weren't one of the lucky ones, good luck for the next round of tickets in April.
