Bad Service by Management/sales person at Lewis Shoprite Park

would like to express my disgust at the service i am receiving from Lewis stores Shoprite Park Cape Town. 2 months ago i opened an account and bought me a lounge suite. i paid that account within 3 days and had it settled immediately. i called the Store 4 days Later to explain to them that the 2 seater and one seater is not in a good condition because its making a spring noise and the hand bar has a dent. i was informed by the sale lady that i would have the item swapped out and the manager confirmed it as well (Daphney). fast forward 6 weeks later i still have not received my replacement. no one at the store calls me to explain the situation but i am being called daily to open up an account again. i called in 4 weeks ago and was told that the Van is going for a service which is a pathetic excuse because i am sure Lewis does not only have one Van. today the 29 July i called into the store once more after several attempts and Evangelique told me they on there way they are at the warehouse LOL and like a fool i believed them once again. now i am taking this matter to the OMBUDSMAN because i am being taken for a huge JOKE and bare in Mind i am a customer. i am being **** to and mis treated. if you check the books/Data you will see i am waiting for calls that was never made to me i am even on whats app with the sales lady and still nothing. the only time you receive good service is when they want to make a sale. all i want is my replacements because my item is under Guarantee and i even took extra Guarantee as well which i am sure the sales person enjoyed in a form SPIV and i want the protector for my lounge suite as promised by Evangelique. i am really appalled by this because Customer service should not only stop when a sale is complete but should continue beyond that as well so that you have successful prospective clients
