Thoroughly p..... off

I have not had the internet for days on end. I know there was a general problem but I only had one message from Home-Connect, stating that an emergency upgrade (emergency UPGRADE? bull****) will be done, during which internet may not be available for two hours. Since then, no internet and no further communication from Home-Connect. Neither are my calls answered. My dilemma is: were the problems with the line solved and I have a local issue, or do the problems with the line persist? I can understand that technical issues do arise but there is no excuse for leaving your customers in the dark.
