Where can I find Samuel , a builder / renovator who lived in Mojácar area and traded under the name “Complete Renovations Mojácar”

I think he still trades under that name.

I have a number of 644815372

I hope that helps

Sam has gone to Malaga area he owes Me 1000 euros and a lot of deposits from other people not a good person unfortunately.

Precisely. Thanks to Gill mr for tel no. which is same one I had.  At this stage it is an address that is required for service of legal correspondence. I understand he is somewhere in the Estepona area trading under various different business names e.g. "Complete Renovations Marbella"  "Complete Excavations Marbella"  "Complete Maderas Marbella" and possibly still using "Complete Renovations Mojacar" Cannot say much more on forum but perhaps can use private messaging facility
