thanks for your helpful PM with feedback, Angelina.
So far the update is, going to do an affidavit regarding the fact that the machines were working when they picked them up and email that to them together with an offer of a full refund if they wish to return everything. My instinct is they are trying to call my bluff to get a discount as I know they were very keen to get hold of this particular machine which they then planned to refurb.
It would still be helpful to have more advice / feedback if anyone else would like to reply.
Hi! Is anyone aware of who owns 52 Lordship Lane (ex Gods Gift) and why so many bars/cafes have tried and failed to make a success at this location? Thanks!
