Sold BC but funds not received into Bank I'm new to BC. I've bought using Blockchain.info, linked to a Coinify account which I've had verified with ID etc.

Buying is fine - got that sorted, but it seemed sensible to try selling a small amount in case I ever want to do this quickly, so I used Blockchain.info to set up a sell order for £10. I entered my Bank details (IBAN etc) as requested. In my wallet I can see the Coinify Sell order, and that the transaction has been 'confirmed'. I can view this on the Blockchain too. But no funds have reached my bank account. Blockchain.info refer me to Coinify, Coinify have asked if I received confirmation from them, which I did not, but now appear not to answer my emails. 

It's entirely possible I messed up the transaction as I'm new to it, but I'd be interested to hear any comments about what I've described so far. It's only 10GBP, but the principle will be the same whether I sell this or a larger amount. Have I gone about this the wrong way?
