Poor service

My name is Silindile Gumede I purchased a Dining room suite, TV stand, Microwave, Stove and a surge plug at Lewis in Kwamashu. I'm not happy at all with the treatment I'm getting it's an appalling customer service especially from it's senior management that I have dealt with thus far namely Lerato and Lisa firstly the bone of contention stems from the stove and a surge plug I have not recieved and no one is telling me a conclusive solution to my problem Im just told there is no stock and the sad thing is I run after the store for an update in the matter and yet the senior management has an audacity and gall to harass me about thier full instalment to be paid and threaten to take goods and yet they are the one who did not deduct as agreed upon now that the installment has been paid no one is updating me about the arrival of the goods that has not been delivered I'm not even offered an option to remedy this situation I purchased these items for Christmas I wanted to cook for my family but because of the incompetence from the store management I didn't fulfill this for my family. I have been patient long enough can my goods be delivered as promptly as possible come January I need to pay a full installment and yet I have not received all my goods where is the fairness in this ????
