PUDO won't admit they made a mess-up

I wanted to book a locker with PUDO and made a payment into my PUDO account on 2 July 2024. I tried to do the booking the same day, but it would not go through. I contacted PUDO and they told me that Payfast was having problems getting the payment across, & to wait 24 hours. I then made a booking the following day (3 July). I did not receive a PIN number to open the locker, so waited another day and checked my account again. It said deposit pending, but the money had been taken from my account. With no pin number I couldn't do the deposit, so I waited another day, thinking maybe there was a delay again. I also tried to get an answer from the support system, but it took so long I couldn't wait. On Friday 5 July, my account said the booking had expired (it's only available for 36 hours). However, I could not deposit the parcel as I had not received a PIN number. I have been back and forth with their support system, and they refuse to give me credit so that I can try again. This package is now over a week delayed and all I get are generic answers to my emails. This is not the 1st time I've had problems with PUDO - a parcel sent to Caledon, ended up in Knysna! If i had a better option, I would use it1
