I've been waiting ** days for this return to be credited to our Macys CC. I ret'd * gowns in one box which was dropped off at UPS ******* at **:**am. Both UPS tracking & Macy's website show the box was delivered to Macy's on Apr.*nd at *:** am and rec'd by someone with the initial "RR". I subsequently had another order with items I needed to return and those items were shipped back *******, rec'd by Macy's ******* and our visa credited ******* so I need to know what is going on with this return. The charges for these * dresses are the only items on this month’s Macys CC bill and the bill is due Apr. **. I shouldn't have to pay for items that I've returned almost * weeks ago. This is the *nd or *rd written request I've sent regarding this matter with no response from anyone. Can someone PLEASE respond? Thanks
