outer drum for a servis m6804w 8kg?

lve only had it 6 months and the servis engineer said a 2p piece has put a hole in the outer drum altho l disagree (how can a 2p get in between the inner n outer drum? (l think they just dont want to repair it grrrrr) its also started making a grinding/banging noise it sounds like the bearing anyone got any ideas what it could be? (lve stopped using it cos the water just floods out rather than drips)
its leaking from the outer drum but all the way round like the joins come apart, so apart from needing a new drum (sob sob) anyone got any idea what has caused it ie a fault and where l could get another drum from
thanks sooo much all
