Changing UK Licence for Spanish Licence - Problems

  Hi can anybody help please.  I am in the process of changing my uk licence for a spanish licence - Alicante Trafico.  The whole process started on the 10th March and trafico say they wrote to DVLA on 15th March.  As yet Trafico have not heard back from DVLA.  We got the certificate (little green one) from trafico but the problem we have now is that we are going touring at the end of May and thought we would have enough time from beginning of March to get everything sorted and are now getting worried.  The UK photocard has now expired hence the change to a spanish licence - will we be legal to go on holiday with just the receipt from trafico as proof of exchange processing.  Tried contacting DVLA who seem to be denying all knowledge of trafico contacting them but trafico insist they did on 15th March.  Help has anybody any suggestions!!!!!
