that was your experience. There are countless cases of:
CS taking more than 14 days to respond to a query (unacceptable)
CS providing the same canned responses that are irrelevant to what’s being asked
CS being inconsistent with the TOS (saying one thing to one person and a different thing to another when talking about the same exact rule and situation)
All of this is widely documented on the forums. With screenshots. By reputable, respected sellers, not some meksells.
Can they be good at times? Sure. Are they, on average, good? I wouldn’t say so. Your experiences are not “the truth”.
