I would go higher up the chain with northcott, insist on speaking with the boss,the bosses boss, the bosses bosses boss etc.I do beleive you will get satisfaction. 80.00 bucks would be well worth a couple hours on the phone. Ifyou feel that you are not assertive enough have an assertive friend or I hate to say it but it works,a male make the calls. Do not hang up till you get satisfaction. They always have a "boss" above them, take names,. You may have to leave voice mails but don't give up they will get tired of it and issue a refund or yardage!
I would also send emails to the CEO of the company.
