The worst after sales service

So we bought our bed in September and paid in full-We logged the 1st complaint and received a set of new bed slats for our Kim bed-I then sent complain no 2 because what was advised is not what we received as the bed base doesn't hold 120Kg per person -We have told the online team we would go instore for a replacement bed-We ave not had a chance to go -No follow up was done by Deco Furn and guess what we are still replacing slats every week.This all for a fully paid order.Pathetic service and Quality.
