Morning Jauntie, have you been for your morning swim? I just finished mine.

Yes it could be white gold painted with yellow gold, although this usually happens the other way round (ie yellow gold is painted with white gold). Sounds fishy to me. If you don't get satisfaction then you could tell them you are intending to go to the police. Definitely ask them if is solid gold and what colour of gold. Is it described on your receipt? It could be a case of fraud.
