Pathetic service

My fibre line went down unexpectedly. I work from home, facilitating virtual training sessions. Therefore I need my fibre line to work! I logged an enquiry and was told by the consultant that the fibre line needs repair by a techniciab. I am working everyday and therefore cannot afford to be without my fibre line - I don’t get paid if I am not online to facilitate the training sessions. They are of course not concerned about the urgency and have not rep**** or let me know when a technician will be around to fix the problem. No further communication or acknowledgement/aplologising for the severe stress they are causing and their lack of proper customer service getting the problem sorted out is pathetic.
