Bad service from Restonic

I bought a Bed at OK furnitures Birch acres on the 31 October 2018 via my mother’s account, the bed had a defeat and I went to the store to report this matter and they promised that Restonic SA will give me a call to sort this out. The bed is a non turn bed worth R8000 and when the man from Restonic called me he was rude and started shouting at me saying I have to turn the bed mind u this bed is that kind of bed, He further went on to say he is actually doing me a favor to replace it,

After attempts to get ahold of the boss named Kobus I sent him an email to speak to his staff and he hasn’t said anything find email below

“Good Morning I trust you are well,

I bought a bed at OK Furniture at Birch Acres on the 29th of October 2018 and the bed started sinking, I asked the shop to have a look at the problem and there was a gentleman from your shop who called me and no customer service in place telling me that I was the one not using the bed properly. Mind you I am in a meeting with clients when I took a call and he tells me he doing me favour by replacing this mattress. I hung up because I am in a meeting and asked him to give me a call once they are ready to replace my bed.

I really do not appreciate how this gentleman spoke to me his name is Alex. I am a regular customer and my parents and I have been customers of this brand and if this man wants to be part of customer service he must work on his telephone etiquette.“ Alex gave me a call back after he heard I called to ask for his boss and said the bed will be sent to me under 3 weeks it been a month and today I called in to check progress and with the same attitude he started shouting and hung up the phone on me.

I would like a refund and full apology from Restonic SA because for the longest time I was the one calling and trying to get this matter sorted and the staff continues to disrespect customers
