The Bedman sold me a substandard bed

I bought a bed in June 2021. After delivery and assembing the bed I sat on the bed and the base was squeaking. I sent email to advise but to this date no response. I sent a WhatsApp to the sales agent and he told me he will escalate the query. To this day nothing has been done and the squeaking is getting worse. Feels like the bed will just drop to the floor. I am very disappointed I am even thinking of approaching the Ombud for help
