Disgusting Customer Service

I mistakenly gave 2 Supporters of my Charity the incorrect lockers - one should have been medium and the other large, I gave the medium parcel the Large locker and the large parcel obviously could not fit in the medium locker. I thought I cancelled the Locker and came home thinking I would ask Pudo to help me change it to a Large Locker. I was shocked to see my Pudo Account showed I had used the locker which sent me into a panic. What happened next became a a nightmare. First I was subjected to extreme rudeness by the WhatsApp Agent who insisted I drive to The Courier Guy Kiosk despite me stating no less than 5 times that I have a 76 year old husband who is dying, I am his sole carer but someone does come in once a month for 3 hours which she did yesterday and that allowed me to go to the Pudo lockers to send 4 parcels but she had left before I contacted Pudo via WhatsApp and I could not leave him alone. I attempted to contact Pudo via the web page - no reply yet. I then emailed Pudo Support - long story short no matter that I am a so called “ AccountSuperUser” they have despite my circumstances refused to assist me and have advised me that I need to complete and pay for a new booking. I am a Government Pensioner battling to see to my husbands medical needs as there is no medical aid and all the bills piling up but this company that I have used to send so many parcels could not and cannot assist me? So much for Customer Care!
