FLAGSHIP ONE,INC WOULD NOT REFUND MONEY TO MY CUSTOMER. East Rockaway New York

WE PURCHASED ECM FROM THEM IN GOOD FAITH. 1ST ECM DID NOT REPAIR PROBLEM. 2ND ECM REPAIRED PROBLEM BUT CREATED OTHER PROBLEMS. AT THAT TIME UPON RETURN & THEIR CHECK OUT OF RETURNED DEFECTIVE ECM. THEY DECIDED THAT THEY COULD NOT REPAIR. BY THAT TIME THE GRACE PERIOD FOR REFUND HAD ALREADY PASSED. THEY REFUSED REFUND. IN STORE CREDIT ONLY. WHY WOULD WE WANT IN STORE CREDIT IN THE FIRST PLACE?? VERY UNPROFESSIONABLE ON PHONE. GRACE PERIOD PASSED AS OF RESULT OF SHIPPING AND CHECK OUT TIME.
