Fibre connection issues

We have been experiencing issues with Home Connect fibre since we installed it 2 years ago First invoicing was an issue then we were cut off because we didn’t pay, received an invoice 2 days later with the date for that date ( how can you be behind on payments if the error is the suppliers invoicing department and get cut off without notice) Since then Sunday nights we have intermittent issues and sometimes no connection Now we have been off for 3 days with nobody being able to assist We just get the sentence around the undersea cable being damaged We are urging fellow citizens that experience issues to raise this!!!
