My Friends, I need your opinions! SERIOUS incident

[AbsolutelyROLEX!]

Hi Fellow Rolex friends, I need your opinion on an incident of which I definitely think it was handled wrongly by the other party (or myself?)

I will politely not mention any names or references to the site to maintain respect and dignity, since this is not intended to bash anyone.

On another forum, I made a deal with a seller on the site to buy a Rolex from that person.

We agreed on a price, and I said I would transfer the money next day.

The next day, I received unexpected news of a close family friend that had passed away, and funeral was that night.

So I went to the funeral, did not come home until late that night, and the person emailed me upset the next day that I had not transferred the money yet nor contacted him/her.
I emailed back explaining what happened, and told the person I would do it at lunchtime.

Lunchtime came, and since I run a 3 bay auto repair shop by myself, things got crazy and I did not get to the bank.

That night after work I checked my email, the person emailed back saying I was Pissing on him/her now and I was banned from the forum, despite me having impeccable feedback and reputation.

At first I could not believe it, was very mad and emailed him/her back threatening possibly even taking legal action, which in hindsight probably was not the right thing to do, I realize that.

I tried to explain myself and make things right, even asking for one more chance to transfer the money in the morning, but to no avail.

I rely on my great business practices and reputation on that forum for future business, and now when others go to check, will see that I was banned and tarnishing my credibility, I think very much not justified.

So I just want to explain myself, and use this thread as an explanation of what happened in case someone has any doubts as to my honesty, and to get your opinions on this.

Thank you all in advance!

***** ADDED ******

I forgot to add in my thread that I had already bought 3 other watches in the past year from this person totaling 17K. We have (I thought) a relationship.
