Regula tuning Regula Tuning, This company are not paying money back what they owe me Gorton England / Manchester

Bought a spoiler from Regula tuning in Germany. I tried to buy through flee bay but was asked to go through PayPal. The service after paying through PayPal was terrible, told me lies that goods had been destpatch via DHL, I cancelled the goods and said I wanted a full refund, They agreed to a full refund, however after 25 emails they have still not paid, they have said things like yes we will pay tomorrow, yes we will pay after the show we are at, loads of promises but no payment. I am also taking it up with PayPal, be carful a very unscrupulous company , and c3rtailnly not honourable.
