Courier guy is a ****!!!!

I used courier guy to courier items for my wedding and I must say I am so disappointed. The parcel was open when it arrived and stickers for champagne bottles were missing. I wasn’t assisted in any way. I was just told by Joy from Vaal Courier Guy that next time, he will make sure my parcel arrives safely. What about my stickers that I wasn’t compensated for? Why was my parcel opened in the first place???
