Pet Supplies Plus review: check to cover sales of tee shirts for 501c3 in Salem, Virginia

I am the director of Barn Cat Buddies and Feline Friends, a 501c3 cat rescue. We have had cats in the adoption center in Salem, Virginia for years and also had tee shirts with our logo for sale in that store. We have filed for dissolution of the charity and our lawyer is waiting on an accounts receivable from Pet Supplies Plus to cover the collection of sales on those shirts. We have reached out to the manager, Kris Patton, at least half a dozen times and we were told she would call accounts payable. After 3 months, we are unable to receive that check. It must be received before we can do our final dissolution. If our attorney needs to contact you, please let me know. The check due is $183.00.
