Disgusting service

I've never seen such a poor service, we've been experiencing a problem with our wifi, we called them yesterday they couldnt fix it over the phone, they promised to deploy one of their technicians first thing this morning, he never came, they confirmed that he will be here at 14:30 when we enquired, still he didnt show up. We enquired again and they telling us that they cant get hold of their technician and no one is available. We working from home we depending on this wifi to work so that means today we didnt work. We need this wifi as in yesterday.
