I am a fbm seller on Amazon as well as a buyer.
As a buyer I recently needed to contact the seller regarding part of an order that had not been delivered.
Normally it is easy but (perhaps) since this was fulfilled by Amazon, I could not locate a way to make contact. I had to search on google and hope I was not contacting an incorrect number
While talking with customer support, I had to give them my 2 step verification code so they could check the order. This was a little scary and not very professional.
It turned out well but my suggestion would be - Make it easier not harder for a customer to reach customer support whether a 3rd party seller or Amazon. This may be why some customers are so upset by the time the figure out how to reach out to us. I certainly was.
I currently make my own templates. Please spend your time fixing something a little more important than templates.
Just my opinion.
