Ongoing Issue with Volt Broadband Speed Boost

Dear Virgin Media Team,

My M550 broadband service began on 16 November 2025. Approximately two weeks later, my O2 data successfully doubled from 25GB to 50GB. Additionally, in my O2 account under "Virgin Media and O2 benefits," I see the message:
"You’re all signed up. Congratulations - you’re all set for supercharged benefits, just for being with Virgin Media and O2."

However, eight weeks have now passed, and I still have not received the Volt benefit of doubled broadband speed. Despite several messages to customer support, this issue remains unresolved, which has been both frustrating and disappointing.

I kindly request your assistance in resolving this matter as soon as possible.
