Cashback tracked and was paid really quickly. I wasn't expecting it to be paid until I'd paid off my balance but I got it within a few months so was able to use it against my balance. Balkan's customer service isn't great and their airline can be hit and miss but we made it on holiday, had a fab time and for what we got it was an absolute steal. Their prices are amazing compared to other tour operators. Will be booking again for sure.
