Delivery complaint

I have never experienced such horrible at Game store at Chris Hani crossing at Vosloorus. Bought a fridge in about November and paid it in 4 installments. A guy was assisting me but because of his incompetence he failed to deliver on time as promised. When I call him , he always opts to call back even though he knows he wouldn't!! Ive paid the fridge in full and I just wanted whats due to me but because he is not an honest being.. I just want a refund and I definitely will not refer anybody to any game store for appliances!! Highly disappointed
