Credit card charge back dispute claim with Wells Fargo bank?

I purchased from Nordstrom Rack a $200 designer item but they sent designer jewelry instead. I reported the issue & shipped back the wrong item to Rack but was told by them that it's not the correct jewelry according to the tag. The jewelry had the D&G tag attached to it with documentation & a case. I was upset as i waited for my refund so i read many reviews about the Rack & how others also got tons of wrong items from what they had ordered so it seems like something is off with their warehouse. Now they are not refunding me my $200 for the wrong designer item even though they received it back & confirmed that they got it! My concern is my $200 now & i wanted to know if I can do a chargeback? The problem is they just deactivating my account with them. My question is if I contact my bank to do dispute, will the Rack/merchant be able to respond to the chargeback on their end because when I contacted Rack to check on my return, the customer service said that she has no access to my account as it's deactivated now, so how will they respond to my Wells Fargo chargeback now if it seems that they also dont have access to my account just as I cant access it myself. I guess from what I understand once you deactivate an account it disappears. I just want my money back because they didnt even return the wrong D&G jewerly back which i would have sold for $200 or less to at least get some of my $ back. Any way to get back my money through charge back?
