Account Hold Question

I placed an online Target order for pickup on Tuesday. Ended up cancelling 5/6 of the items, left me with a $13 total. There was a hold, but I expected that and waited. It has now settled for the final amount at Target, but the damn hold is still on my account. I chatted and was told to call because customer service over the phone could release the hold. Customer service over the phone told me to just wait, it would settle in ‘7-10 business days’.

Why in the hell am I still waiting on a hold to be released when the MERCHANT has already settled?
