i submitted an online dispute with transunion....came back 1 item was deletd, however score remained the same so i was wondering, do i have to wait for them to update?
Nope. It should be gone immediately. Are you sure you are pulling an updated report? Your score should definately reflect the change. Perhaps this is related to the current issues at TranUnion. I would not panic.
I have noticed the same thing but since each bureau is different because not all creditors report to all bureaus it may be the impact doesn't affect TU as heavily as a perhaps more used bureau. For me all bureaus have gone up with tu the highest yet not so much as drastic as the other two. I still am expecting some changes soon due to payoffs and aging. It could take longer than 30 days if your creditor already updated this month.
