Crazy Shopper!

About a month ago I made an online purchase from clicks. Everything went smoothly up until the day of the delivery. Upon the arrival of my package, noticed a very strong smell. When I opened the box I noticed one of the items in my box was damaged and it caused a hole in the package. This damage caused one of my the packages that was in my order (at the value of R563,98) to slip out. Luckily the couriers was still outside, I quickly rushed out to ask them for my package. While busy with the driver I explained to him that my box was damaged and that one of the packages within my delivery must've fallen out. The driver then immediately acknowledged that he saw my package and that he placed it inside of somebody else's parcel since the liquid that leaked from my package damaged that parcel and he assumed that the items fell out of that parcel (and not mine). I understood him and know we all make mistakes. While busy with the driver the assistant got out of the bakkie and questioned me, I didn't pay him much attention. According to him I he asked me if there was any damage to my box and I said no. I don't really know because I was busy dealing with the driver and solely focused on the driver. Following this the driver got my package out of the other parcel and was ready to hand it over to me. The assistant , without explaining me any of their company rules or regulations became very rude and said abruptly you cannot get this stuff. I became very agitated because I couldn't get the stuff that was rightfully mine, that I payed for. The driver then told me I'm going on over hair stuff as if I didn't have the right to ask for the stuff I payed for. After this the driver went on and called me crazy,he repeatedly told me that I am crazy. I then called ram to complain about this incident. They said that they will look into it and call me back. After that I phoned them about 3 times to find out what happened to the complaint. I was told that they were going to phone me back. It's been a month I'm still waiting for their phone call. I just want to know what credentials that courier assistant had to call me crazy and if he or Ram knows that that is a serious offense.
