Totally despicable service

I have been trying to get hold of Thekenwoodboys, whom it seems are the service agent, for DeLonghi for 4 weeks now with no reply. I have emailed, telephoned and whatsapp with no success. I paid them for a spare 7 weeks ago now, and they simply ignore me. As far as I am concerned this is out and out *****. I have also sent two emails to yourselves at DeLonghi with no reply.
