bad customer service feedback

I bought Fridge at Mikro Woodmead they promised to deliver my fridge the next day , no delivery or phone call from them called several times was sent from pillar to post the cashier never gave me the invoice for the fridge to be delivered , it seems to have gone missing in the store , I don't know why as a client I have to suffer for staff mistake as I don't know how process works, im fuming as I have been waiting for my fridge 3days now still No feedback from Mikro Woodmead , I had to drive all the way from Boksburg To Woodmead wasting my time and still was told they gonna follow processes , I really just want my refund back for my fridge .
