cassims collections are terrible disappointing service - only a convenience!!!!

I chose my curtains and lining when I was at cassim collections 2 weeks ago. johanna is the person that assisted me. I had a strict budget to adhere to and made this clear to her many times. the lining that i chose was the R45/m and off white. however she had forgotten to add this to the receipt and i made payment. when i reached home I called to confirm my measurements for the curtains, it was then that she said that I had not paid for the lining. I indicated that the lining should be added to my bill. I collected my curtains today and was extremely upset and disappointed. johanna used the wrong lining which is white!!!!! and there was a distinct price difference, it was R56/m!!! I will not shop at cassims again. the ladies are unfriendly and rude and rush one into making a decision!!!! i would rather drive to Vereeniging rather than consider the convenience of cassims as that is all that they are!!!
