Complaint Sleepmaster N1 City Cape Town

I have been trying to get my bed exchanged for over a month now. The manager of the NI City stall is always in meetings and not available to speak to their customers. I have firstly been back to the stall on 25 May 2022 to lodge my complaint. On 25 May 2022 I spoke to the sales lady. I had to send her pictures on whatsapp, On 31 May I asked again about my complaint been resolved. I was told the complaint was sent to the resolution centre. From there it goes to the supplier and then I will be contacted. On 7 June 2022 I enquired again with no success. On 8th June I went back to the store to choose another bed. I was told I would get feedback the next morning. On 10 June I tried to phone Searly directly without success. I was whatsapp to say my complaint was resubmitted to the resolution centre. On Friday 12 June 2022 I wrote a complaint on the head office Sleepmaster website and received an email the next morning with a reference no. Today 13 June I phoned the head office and was told by the clerk that normally the store would exchange the bed if the customer was not happy!! Wow and I had to wait all this time to hear that it was that simple. I then called the store again and demanded to speak to the manager, when I was told he was in a meeting and expected back in the store at 1530. I phoned the store again around 5pm only to be told the salesperson had left but asked the manager to check stock and confirm delivery. Well I am still waiting for my call!!
