Disappointed in The Courier Guy services rendered

I ordered a parcel to be collected at Masterparts Montana Pretoria on saturday 1st October 2025. I paid R109 for the parcel to be picked up and dropped at the locker at Obaro in Tijger Valley Silver Lakes. I drove all the way to the locker once I received the pin code via whatsapp. When I tried to insert the pincode,it kept saying invalid code. I called The Courier Guy to advise them. They told me that it is a technical fault and they will get a driver to come open the locker and call me back. That was Wednesday 5th of October. Siyabonga Dladla called me and said they will deliver it now to my home address. I've sent him the pin location ( I stay on a smallholding) He said they will deliver it. Then I received emails and messages from the courier guy company to state that I must pay a further R120 for my parcel to be delivered!!! I feel it was not my fault that there was a technical issue at the locker!! I don't have R120 to pay, ad I explained to them that I am currently unemployed and my mother have helped me pay the courier fees and petrol to drive to the locker. The waybill number is JJQCFH. Pin code provided was 224821.
