Disgusting "Who cares" attitude from Experian

I logged a dispute in September 2020. Experian then responded with a table of information they required, which I filled in and sent back. The simply send me the same email back again asking for the very same table of information. I tried calling them, but it is impossible to get a hold of an agent. I was left with no choice but to return the email with the same information I sent. A coupe of weeks go by with no word from them - then AGAIN THE SAME RIDICULOUS EMAIL ASKING FOR THE VERY SAME TABLE OF INFORMATION - three times in a row, with no update to my records. By all the similar complaints, they really don't seem to care. "So what"- is their attitude. It's disgusting - how do you send me the same email 3 times in a row without updating my credit records??
