Granted, red flag, but way to early to start a thread. He started the thread less than 48 hours of paying.
I never started a thread in the WFS in my first 7-years on this site because I felt that I was just too busy to communicate properly.
So for 7-years I just did deals in the background here on AZ, sold a lot of stuff, but even then I had to make an effort to communicate, and many people are impatient.
There were times when I would decide to work at home just because of cue deals, and even then I would get busy and forget to call FedEx for a pickup.
Sometimes it would get down to crunch time, and due to my limited shipping supplies I couldn't get it done, and it was communication that got me by.
Once retired I started posting threads in the WFS, purchased $200 worth of shipping supplies, and now it's easy, but for 7-years I completed well over 100-deals unscathed, and many times is was my communication skills that saved me.
You would not believe how many pm's I get, and it takes me longer to delete the old ones, than it takes to respond to the new ones.
If you post a cue for sale and someone makes a Paypal payment, 48-hours with no response is too long.
Whether or not 48-hours is long enough to start a thread depends on the situation, but when communication stops after the payment is made, people get real concerned.
Sellers on AZ Billiards should do what it takes to make the buyer feel comfortable after the payment is made, and maybe even before if you have any sales / marketing skills.
When a buyer feels like he is getting porked, he is going to start a thread, and there is no timeline or chronological order on when that is appropriate.
It is our job as amateur online broke-ass sellers to make sure this doesn't happen.
