Right I'm posting this so the situation is transparent and I cant be accused of anything underhand, Tom contacted me this morning at about 1100 to deal with the situation, it turns out that the money I paid for the PM8 has been spent on an Ego. Tom assures me that he and his dad do not have the means to reimburse me for the marker so the only option left was to knock money off what I paid. We have agreed that Tom will pay me back £30 which his parents have had to lend him and is the most he can do which he gave me his word on. Although dissapointed with the sale I feel that this is the best that can be salvaged from the situation.
