Is Seller Courtesy Dead?

I am a regular buyer(collector) of one product predominantly from a couple of US sellers who have good product ,good packaging and good shipping costs. Occasionally something goes wrong with an order:never sent;or wrong item sent. As a matter of courtesy I first contact the seller advising of the situation.Invariably the only response from the seller is a deafening silence.Or in a singular instance a return email from a real person promising to research the order-then a deafening silence.

 

Am I naive?Should I just initiate a dispute and communicate with the seller through that medium?

 

 I am hoping that by posting this message sellers might appreciate that: regular and fast paying buyers need to be treated with courtesy and respect;communication costs  very little but earns disproportionate dividends;and any complaint should be viewed as a potential gift because it might improve a seller's business.

Incidentally I always provide feedback to sellers-usually positive.And I frame my email communication to the seller in unemotive and factual language.

I am now so frustrated with sellers' non communication that I am considering alternative strategies for my collecting.What I would dearly like to say to these sellers is:get a quality management system into your despatch areas;and communicate with buyers who take the time and effort to communicate with you outside the dispute process.
