Wrong pin, and no one is willing to rectify and take responsibility

I received a collection pin on Friday (3/6/22), went to the locker just after 14:00pm, only to realize that I was given the wrong pin and the parcel was not mine. I called the call centre number from 14:15pm, no one was able to assist me and tell me what's going on. I drove around with a stinking box that was not even mine, with raw fresh fish and other funny stuff inside, it was creepy. I had to wait till 17:00 hoping someone was going to make a plan to collect the parcel or even give me a pin to deposit the parcel back to the locker, the last person I spoke to was Courtney who promised to get back to me, but when I called I was told he had gone home. I am beyond angry. Your service is disgusting, your staff are ***********, and you do not deserve to be supported at all. Till today no one has called, contacted me in anyway, I decided to leave the parcel outside the locker, took pictures and sent it through via e-mail (***), to show that someone needs to collect it. I cannot be spending so much time, energy and my airtime trying to reason with ***********, carefree and stupid people.
