Mate you need to lower your expectation of the reps we buy this aint the same a going into a shop etc. We are lucky (arguably spoilt) by the trusted dealers here.
These are trusted in so far as they wont scam you The fact they sell these on the basis these are reps and arent perfect, you take the best you can get and make it better thats the game
Be happy with what Mary is giving you mate as for a service etc That just wont happen you could find GF that when you get it it wont work or wont reset or DW wont change etc etc It happens thats our world It aint perfect but our TDs will take it back if you send it and will replace it but you will pay for P&P etc so its cheaper to do the service it needs rather than bother going thru all that again, hopefully you understand what I am trying to say
This is rep QC not the QC we all understand as Western Consumers etc. What you have now from the dealers is night and day from how things use to be !! I remember my dad putting me on his knee and telling the old rep horror stories !!! Or was it Don :) ??
