Bad Communication

Received a broken product, sent it back and asked for a RETURN of the same product. Noted today there is a credit listed on the account. Was informed telephonically 1- There is no stock. Then all of the sudden there is stock. 2- Then they cant order for me, then they can. Then I must pay delivery then I was informed they will find out for me ? It is now escalated, what & how - I dont know ? Why must I be liable for a delivery fee ???? Poor poor communication Take a lot
