Shocking service!

My husband bought me a lovely cushion from @home Sandton around two months ago at the cost of R499. After a month the beads began to fall off. Eventually I decided it would be better to return the cushion before it lost all of the beads and too much time had passed since it was purchased. The manager at The Glen branch was rude and unhelpful! She said because I did not have the slip (it was a gift from my husband) she could only give me R99 as they were now on sale! My daughter, who is a lawyer, tried to explain about the consumer act but the manager said she did not care about the consumer law. This is disgusting!!! I would like a full refund and an apology! I will never purchase any again from @home as obviously their goods are low quality at a inflated price and they do not obey the law! Unless this is sorted I will go to the Consumer council
