****ED OFF AND DISAPPOINTED

I am very ****ed off for the service I receive from IBO. The service I got the time I buy from them was so smooth. I returned one item from my order, they are now taking me from pillar to post for a refund. I have been calling them enquiring about the refund, I was told it takes 5 days for the refund. It is full two weeks but my refund is not done. I called yesterday, 2024.12.04, the guy I spoke to was very suprised he even said it is too long now, he went to enquire from the manager about my refund, he then came back and said the item returned they never received it. I don't know how because they are the one who sent the courier to collect the parcel, n it was collected. It was for the first time I ordered from IBO, n one thing for sure it is for the last time, if that is how they treat the customer
