Worst service ever

On the 13/12/2014 me and my wife went to Morkels Parow to go and lay-by a bed that was on sale.It was a Slumberland Marlow base set for R3999.So we put R1000 on it.3 days before we went to pay the last R1150 on the 28/02/2015 my wife got a call to say when are we going to come and pay the last so we could get the bed.i made the last payment on the 28/02/2014 and went to the store manager to ask if they could still deliver the same day.The manager said that there is no stock,so we spoke to our sales lady(joan) who said we could get a bed but had to pay a extra R500,so we said no.Later that day she phoned to say she found one but its a demo unit in Somerset West.We said no as we payed for a new bed factory sealed.She then phoned to say she found one in the eastern cape and if we would wait 2 weeks to get it.So we decided to wait.On the 14/03/2015 i phoned Joan to ask if they had the bed as its been 2 weeks already. She said that she does'nt have the bed and that we can wait some more or get our money back.We decided to get our money back as we felt we were treated unfair as we had a lay-by but if we took the bed on account we would have had the bed the same week.WORST SERVICE EVER
