Restonic Barbados bed

I placed a lay by on the 19nth of September 2023, I made the last payment on the 23rd of December and the bed was delivered on the 3rd of January 2024. Firstly I was told that the bed had no springs and that restonic is one the the best brands. After a week using the bed it started making squeaky and creaky sound. I went to the store to report the fault I spoke to the store manager. Told her about the fault and told her that the bed has springs which I was told it did not hence I chose to buy it. The store manager logged a complaint with restonic because the brand is from restonic. She then said I would receive a call from them in a few days. I received a call at work and the guy did not bother introducing himself or where he was calling from. He asked for a person I did not know and when I advised it was not me ge dropped the call.. I called the number back and he only mentioned then where he was calling. I advised him I am not the person he is asking from however I do have a complaint with restonic. I requested that he calls me back he never called me back I had to call back again twice that day. I got through to a lady who took down my details and transfered me I asked the guy again to call me back. They never did. I called back the 3rd time and the lady pretending like she was taking my details down she advised she was transferring me, placed me on hold and dropped my call. I called the sleep masters manager and she said she would sort it out. She requested that I send pictures of the bed including pictures of the base. I sent pictures and she I would receive a call and a message to say my complaint had been processed. Till this day my complaint has not been looked at or processed. The guy called again and asked for the wrong names. I informed and asked him why they keep asking for the wrong person. He then said the complaint invoice was sent with these details and that they would need to resend the correct invoice. I called the sleep masters manager. I am the one who has been using using my airtime to call these people they are not bothering, the most appalling service I have ever received. It is like they are doing this on purpose so that I end up getting tired and drop the case. I cannot drop the case because I bought the bed in a legit store to avoid having a bed that will give me problems, I bought the bed for 5850 including delivery because I wanted something strong. So when I informed the store manager that they had said an incorrect invoice was sent. She then said it must be an error made in the head office. They have been taking me for a ride all along please help me
