Thanks everybody so much for your advice and well wishes. As an update, i took him to the vet who told me pretty much the same as what i already knew and charged me £25 for the pleasure, but he did suggest that i effectively force feed him by nudging his mouth open and popping his food directly onto his tongue (not down his throat). I have been giving him waxworms by this method that have been fed on a supplement. I also pop one or two crickets in to his cage from time to time to give him the option. he has eaten a couple of crickets this way, and takes the waxworms without much fight. It's not ideal, but he is at least getting nourishment and is still with us. I'll keep doing this until he starts taking food from his tank on regular basis.
On the pet store topic, mine is pretty good, but she admitted that by this time she was a little out of her depth and thought it best to take him to a vet to make sure there was nothing we were missing.
