WAS BANK IN COMMUNICATION. AWAITING REFUND

I settled my term loan on 9th May 2020. I sent them my settlement letter on the 22nd May cause I received the settlement letter in my spam box on the 18th may however I call them and they said it was noted in there system that no other deductions will happen. End May they deducted, fine cause the guys said if it happens it takes about 7 days for refund. It is more than 2 months and no refund, however they said instead of refund they closed my account, They bad part of this whole issue is. NOOOO COMMUNICATION. NO ACKNOWLEDGEMENT. Yes its pandemic, yes they could have short staff, but come on man 2 months of no communication. SO I AM STILL AWAITING MY REFUND. I mean it took me very long to settle my debt.
