Hi,
There is a problem with the DSL connection after transfer of the contract from previous tenant to me. Tried contacting the customer service but no luck apart from creating the case with no: 900419430478. I have attached the pictures showcasing the current router status, O2 service app diagnostic status and the Case created chat. The issue persists from April 8th.
