Disgusting service

I have had two incidents where the jet in Greenstone and eastgate have treated me poorly and I have had enough. the first incident I went to greenstone to return an item which I felt was not of high standards. (pair of pants that lots its shape after one wear) I went to the counter and the gentlemen who was assisting me told me I had to go to eastgate where i bought it to return it because they do not stock the product. I said no and that they must return it there. his collegue got aggressive with me Thokozee I think that is is name. he spoke to me rudely and I was so shocked. finally the manager got involved and assisted me Nomusa. she was pilote however I still felt that Thokozee was rude and shouldnt be working there. Second incident happened at eastgate.I went to return another item and i waited in the front of queue for 5min because their were customers with allot of goods. there were about 4 open tills that were not working and staff just wondering around. I ask the cashiers if there wasnt someone else to assist me and they just ignore me. eventually i got to the till but instead of receiving an apology I just got attitude. i am so shocked at the service I have received.
