over the past few days I have placed a couple dozen orders

I placed 2 orders last night before I went to bed and I woke up this morning to see that they were automatically canceled. This was after I had went through and canceled some other orders that I decided I did not need.
I think over the past few days I have placed a couple dozen orders and canceled quite a few of them so I must have flagged something in the system.
At this point most of my earlier orders are still intact and I really don't need anything else now anyway.
The lady I spoke with from overseas about it the problem said she would escalate the problem to their IT and I should be able to use the account in 24 hours period of course by that time the sale I think is over.
I'm not sure who flagged me the credit card company or targets website? They didn't seem to know either.
Since I have my target redcard linked up with my account to get the extra discount I didn't try using another card but I think it was the credit card company who flagged me.
