Bad customer service

I'm an online buyer! Buying online shouldn't be a headache. I've been happily shopping everywhere without hassles until i recently tried buying at clicks online. I opted for click and collect, i went there to collect and was told the parcel isn't there yet. 2nd time i went, i forgot the phone which had "Pin" so once again i didn't get this parcel. 3rd time i had the pin but forgot the id in my car, once again i was told even though everything is here except the copy of id am not getting my parcel. I then asked to cancel the order, i mean the same thing i paid for and now struggling to get is also sold at dischem, edgars, and foschini why i should beg clicks to have my money became a mystery. The store manager told me i must cancel it the same way i bought it, I am here online guys, there is no option to cancel the order? Please help me cancel and get my money back urgently, thank you.
