Can anyone recommend: Air Con repairs

Well I have finally given up trying to find someone who is prepared to isolate our air con issues and repair the system at out house in Palomares. I have had several people recommended, the latest being "Jason" in Mojacar, and not one has gotten back to us to arrange a visit despite us being happy to pay a call out fee.

We are very disappointed and somewhat disillusioned that none of the local tradesmen have reacted to our request. It seems to us that nobody wants the work which is hard to understand.
