Worst customer service in 20 years, fobbed off, CLUELESS...met with 'errm nothing I can do'..' I don't know'..' Visit the Voda store'!!... so incompetent!! Spent almost 1 month trying to get my Samsung S6 unlocked from their network. Provided NUC code..doesn't work on its own, also need an MCK to unlock. Spent an entire afternoon phoning Vodafone..problem unresolved. Vodafone didn't have a clue what I was referring to? They even told me to phone EE for PUK..I know this would not work as the phone was locked to Vodafone network and Vodafone also told me phone Samsung to have the phone reset 😡??Spoke to Basam on 26/1/2018..clueless text me a master code, but this would reset my phone..I didn't use this..she also said she would call me back in 2 hours..no call back 😡😡. Eventually, I had to get the phone unlocked through a 3rd party @ cost, but provided an MCK and NUC with step by step resolutions to unlock..and it worked. Spoke to Mohammed today 27/1/18 to reimburse told me nothing he can do..clueless and told me to visit store. Vodafone complaints apologised for poor service and inaccurate information..but refused to redress and compensate & stated they will give me £20 'as a goodwill gesture' will not reimburse £32.39 for cost incurred to unlock with third party...rude and patronizing. NEVER use Vodafone AGAIN!!
