Hello!
I have been recently in contact with a certain e-mail adress, sent and received several messages.(It is a customer support to a certain product both hardware and software, so an official adress) After a while, I did not receive any new e-mails from said
adress, even though I tried to send them e-mails, and open new tickets on their customer support website.
After weeks of unsuccessfully trying to make contact via e-mails, I contacted forementioned customer support by phone, and they claimed that they did not receive any of my messages. They told me to try and send me response, and I checked for it in real time,
and I did not receive the e-mal they claimed they sent. They even tried to send an e-mail to a different e-mail adress of mine.(Which is also a hotmail(now outlook) account.
The two adresses they tried to send to are:
ldesu78@windowslive.com
kutsera.shaman@hotmail.hu
What could be the issue that makes me unable to receive e-mails from/send e-mails to this certain recipient, after I have had been successfully doing so for several days?
