I confirm a personal message from Gareth at Bitinstant with a vouchx code. I have redeemed the voucher.
Thankyou Gareth. My issue is now resolved.

In regards to an email and spam folder. I do not believe the email was ever sent. I have never had an bitinstant email inthe past go to spam.
Either way, I am happy this ongoing issue is now closed. Lesson's learnt on both sides no doubt.

Regards
