Hi i puchased the second batch of vidz on 17/2/2010
studio accoustics
digital & computer
microphones
keyboards

on the 17th Feb there were 4 vidz uploaded which i purchased, only to discover the following day 18th that the bass & monitoring vidz was added as a 6 vidz package for $19.98

i payed extra £9.98 for the 2 extra vidz

is it possible because i bought all 6 vidz, that i will get re-inbursed

thanks j dan

Hello there,

Absolutely no problem. We're sorry that the Batch 2 upload was so staggered but technology demanded that unfortunately. Please can you contact orders@keyfax.com and request the refund and that will be done right away.

Thanks for your support. We certainly don't want to penalize you for it!
