In short, the UK Gambling Commission doesn't solve consumer complaints, but on the other hand, makes sure that all licensees have effective procedures that could handle such. You can count on customer support and complete transparency in dealing with any issues you may encounter along the way. In the case of a dispute, licensed operators are obliged under the terms of their licence to refer the matter to an independent third party. The UKGC can and will perform a check only to confirm whether a betting firm has met its obligations only in so far as the operating licence is concerned.
