Bad service, no refund as promised.

The worst service ever. On the 15th November 2022 I ordered car part online unfortunately it didn't fit. They took it back to exchange for the correct one, and they were supposed to call me once they got the part. Two weeks later, I asked my father who returned the part to go back to them to check what the delay was, only to find out that the person who took the part was no longer there but they didn't think of calling me. So they said they will refund since they didn't have the part anyway . That was first week of December 2022. I have been communicating with them via email they keep promising to refund me but to date they haven't refunded me. DLKUHNXJF
