I suppose a condition rating that was lower than 5.0 could be addressed and corrected. However, what about a packaging, delivery time and communication. I know you are not addressing those at this point, but they all go into the overall rating, of which yours is still 5.0. You can't fix those after the fact. I
f you misrepresented the condition of the items you were trading, even if by mistake (small flaw unnoticed by you perhaps), it's still not unreasonable for someone to grade a trade partner fairly and honestly. It would be nice to work out the issue, but maybe that is considered a hassle to the other party?
There are always reasons for poor performance in any of the categories. Some avoidable, others not. Some minor, others major. Some unexpected, others planned. There is a basic expectation with regard to trading: You get the item as described, packaged for safe delivery in a reasonable time frame. If one can't trade under those circumstances, other than an outright emergency that is communicated appropriately, then they should expect to see a low grade here and there. Communication is important too, but I think it becomes even more so if there is an issue rather than a plain smooth trade. Often times, the trade itself, the payment and the feedback are my only "correspondence" on trades. There was no need for anything else.
