Switch from 5G to home DSL/Fiber

Hi,

I subscribed to the Unlimited 5G Package 300Mbps, however, its been since March that internet at my home address does not exceed 200kbps, yes “Kbps” which is not usable,

I tried to cancel contract with tickets, calls, Post, no success, 

O2 keeps saying i have to wait for the 2 year period, 

I pay ##$ monthly for nothing really,

My Question : Can I switch to Home ADSL/Fiber Contract instead ? for the same duration.

Please send me an offer on Email if possible , but it must replace the 5G contract, 

Thank you
