Bad experience at Solo Shoes Carnival Mall

Evening

I have bought 2 pairs of boots on the 22nd of April 2018 at your branch. The one pair of boots had torn and my daughter had it on today for the 2nd time. I enquired via email (25/4/2018) to Carnival branch and to Customer service about this as I do not have the original slip, but I at that time still had the box and I wanted to know whether they will accept it with only this info. Up and till now, I have not received any feedback. I then went to the branch on Saturday 12 May 2018 and the sales ladies were very rude to me and my daughter and refused to assist me. I had the boots with me, but my **** had thrown away the box in my absence as I was in Durban conducting training. My daughter then asked for their names. This is not the first time that I had a bad experience at Solo Shoes Carnival Mall. All I want is some service and to exchange the boots.
