PUK code problems

[#1]

Good evening,

I've received a new SIM card today to replace my old 3g one (all Plusnet).
My phone accepted it fine but when I tried to password lock it, I accidentally locked the SIM and it is asking for a PUK code.

I've retrieved the code from my online account but the phone says it's wrong. I've also called Plusnet twice today and was given the same PUK code but it's not working. The person on the phone has no idea why and was trying to blame my phone. I've only got 2 attempt left and I've tried the code plus all the default SIM PIN numbers they suggested.
Can anyone help, please?

- Your mobile number

- Your full name

- Your full address, including the postcode
