*********** service provider, empty promises

I reported my router with a defective power cable constantly for 4 weeks, speaking to the customer service personnel, who keeps promising that the matter is escalated - as urgent, and Iwas also promised a refund for the time being down without internet. None of it happened. Still without wifi and internet. No refund either. We explained that our business is getting seriously affected by this lack of service, as our guests review us now negatively for a wifi service advertised in our airbnb which is not there, also since the TV needs internet to work. This is serious serious incompetence which is totally not acceptable. Paying for something that is of no use and costing us badly.... Seems worse than the electricity issue in the country, which is by the way the reason the wifi router's cable packed up. Sooo FRUSTRATED!!!
