I can't text people. Chat support reports the problem but they don't solve it. The problem has been going on for two months
Do you mean you can't respond in Messages to buyers?
@ITALYARTT: If you mean Etsy messages instead of texting, what error message are you getting?
If you are getting the "Bummer, your messages have been temporarily disabled" advisory then your account has been muted. If this is the case, and not to discount the fact that your messaging may have been disabled in error, generally it is because the system has detected that your account has been sending unsolicited non-transactional messages. While you are waiting for Etsy to reactivate your messaging you may want to read the "Dos and Don'ts of Communicating With Customers" https://www.etsy.com/seller-handbook/article/26590492608
