Sorry, only just remembered I'd asked for further info regarding this!
Do you have the company, who you booked the tickets with, address? Maybe worth sending them a letter, recorded delivery (where someone has to sign for reciept of it)
The reason why im saying this that you really need to know the booking details ASAP Whilst you now know it's definitely been booked, you need to know that all the details are correct, for example the exact spellings of all your names etc. If any details are subsequently wrong when you get to check in, the best case scenario is that you'll have to pay admin charges to get them corrected, the very worse- you can't fly.
If you can get hold of the details well in advance of you flying you can more than likely get them to correct any errors free of charge, however the closer to the flight date you get, the chances will be slimmer and then none existant.
Good luck
