Poor service: Dissatisfied customer

I purchased a restonic bed from Bradlows online, which was delivered on July 16, 2024. Upon opening the bed after delivery, I noticed that the bed’s base was damaged and the mattress stitching was coming undone. Unfortunately, I haven’t received any assistance regarding an exchange or refund. I’m quite dissatisfied with the quality of the bed, especially after paying cash. I tried several times to engage with their customer service but they keep on saying they will get back to me.
