I was hoping they would be gone asap so I can re apply for discover it. lol
Every dispute I've initiated in recent history has taken the full 30 days, with one TL on TU being the exception.
Just remember there is the +180 days that can come into play with thise. However I have noticed that most will just fall off in 7 years.
OC is 7 years + 180 days max on the CRTP. But most delete after just 7 years. I would follow the drop off date that is listed. So by June they would be deleted.
