Exactly what ‘laws’ do you think have been broken ?, it’s not the case that someone with a sub 10Mb Universal Service Obligation download speed , simply waits for BT to do something or start paying compensation,
you are at liberty to ask BT for a USO compliant connection , that will provide 10Mb download or better , have you applied ?, once your application is made , AFAIK , it can be 12 months for BT to come up with a solution and another 12 months to ‘build’ whatever network is required to get you 10Mb , before you have a claim for compensation, plus as already advised if the mobile 4G service in your area is capable of providing the USO speed , you are already USO compliant, and BT don’t need to do anything as far as the 10 Mb download USO is concerned.
