Thee worst company ever

I did a laybye in September for a lounge suite and paid it in full in October, when i called to enquire about my delivery tbey told me i needed to wait 18 days for stock. On 1st December still no delivery they said stock will arrive 3rd Dec and delivery will be done by 6th Dec. Today is the 6th and still nothing now they saying that stock will only arrive on the 10th December.... This is the worst experience ive ever had, how the hell does a customer have to wait 2months for a delivery??
