Poor product & poor after sales!!!!

I bought a bed at the bed shop in Durban north which is now closed in 2013.....After a year I could feel the springs on the bed am only a person of 50kgs do you think I can damage a bed so fast....I did contact the bed shop newmeros times. But was going around in circles to get someone to assist me so I just let it be because I had no airtime or time to waste. So on the 20th February 2019 gave I called again due to me having a baby and the sleep was uncomfortable they gave me a Neils number I should WhatsApp him so I did he said I should send him the money invoice due to my bed still having warranty on it so I did that he said that he will come and inspect the bed,on the 17th March 2019 I messaged him again to inform him that I am still waiting for him he then tells me he no longer works for the bed shop and will forward my information to the bed shop.i also informed him that I will be relocating and need my Matt to be inspected asap because couriers was going to pick up my things at the end of march now I already relocated to Cape Town and still don't have bed due to this useless sales rep that the bed shop got anyways I messaged him again on the 28th March and told him that no one got Back to me he gave me the number the following information "Ryan at Springfield branch ********** 361 I have send the details to him" I then call the shop and spoke to me Ryan he asked me to WhatsApp him the invoice which I did he just reads with no feedback and today already the 7th April 2019. I had to leave my bed at my boyfriends house for them to check it but still no one wished to do they job what are they getting paid for ??? Who is going to pay for my courier now??? For the mess up!!! we are now in April still no respons from them.The bed is really making my back sore....The bed is still under warranty.I really don't know which way from here. People are fast to make a sale but doesn't care to help on the after sales. Worst service ever!!!
