Poor customer service and maladministration

I changed my delivery address on 03 May 2023, but these guys went and delivered my parcel at the old address today (16 May 2023). This is after confirming several times with their contact centre that the new address has reflected so they ensure to take note of that.

I then call the contact centre to make them aware of this and while they agreed with me that the change was done on 03 May and that it was their mistake, they expect me to incur the cost of them picking it up at wrong address and delivering it to my correct address...seriously?

As for the contact centre team leader, they promised to return my call and still have not - it is clear that customer experience is not top of mind for UPS.
