TARDINESS IN REPAIRING/REPLACING SLEEPER COUCH

I had bought a Retro Blue Sleeper couch and discovered it a faulty arm rest. I tried to have it replaced and it took over 4 months to have it collected. The couch was collected on the 12 Feb '24 and it was to be repaired or replaced. I did a follow up on the 23 Feb '24 on the status and I was informed that the couch is still at their Cape Town Warehouse and it yet to be taken to Johannesburg for repairs. They predict it should be ready by the 04 March '24 but this not a guarantee. I am so frustrated as this is taking much longer than anticipated. I am not sure why Dial A Bed doesn't just provide me with a different couch as there is tardiness with their repairs
