My postcode and work postcode couldn't be found on the system, so emailed to see why. The postcode was valid, so I had to be sent an invoice, which I could either pay using a website or a bank transfer. I chose the bank transfer, and put the correct invoice in the reference. The money went out of my account, but still hadn't heard anything after about a week. I emailed again, and was told that the company hadn't received it yet. I had to email again with my sort code, account number and the reference before FLAB checked properly, where they found it. I assume it had been sat there for days without being checked. Nightmare exchange in all jonesty, but the products are good. Just a number of different errors along the way that left me extremely frustrated and angry.
