Really? Tucows have completely ignored me and are scammers must the same as Hostbig who cannot be trusted at all. If you host with any of these providers you are risking your money and reputation. ICANN are of no help either and are complicit in the fraud with Hostbig. The whole domain industry is set up to sell, sell, sell domains (did I mention sell?) and if anything goes wrong they don't care and will not help you. It is legalized fraud and they are all corrupt to their back teeth.

I dare bet your domain was bought from tucows who are a domain wholesaler
That is who my domain was with very approachable and always answer emails
