Jenny Internet provider the worst ever

It’s been 3 days and counting without internet, I’ve called numerous times spoke to agents the ones who answered can’t give me a reason why they offline and every time I call they don’t answer or advise that they will get back to me. 90% of the time we have no internet connection and we have to pay them a full instalment monthly. They have no customer service etiquette, not interested in their clients at all. The more I advise them that I work from home and unable to work due to no connection they advised me to get backup but we paying for a service. They can’t advise you when they will install fibre. The worst service provider ever.
