has anyone dealt with a ebay uk store called imdpistons , bloke called Adrian ,order a set of rings before xmas , heard nothing until I enquired about 1 week ago and being given the run around since ,because asked about a later set of rings first before ordering and paying for a mk 1 and 11 set , said was waiting on me to get back to him as the later set were the wrong ones ??? which I knew, been back and forth since .. keep saying i want the ones for the mk1/11 1946/47 350cc , and he keeps asking am I sure their the ones I want ??? don't know whats going on but seems strange .. his store has sold a lot of items (profectional) with a good rating , don't know if should persist or go for a refund
