My biggest regret

This is certainly my biggest regret in 20 years. Changing my internet service provider to Rain. For the past three months around this time of the month AND ALWAYS ON A WEEKEND there is no internet connection for the whole weekend. When contacting them you spend hours on the phone trying to reboot, restart, change towers etc but still the issue is not resolved. The answer is always the same: you ate connected to your secondary tower, the primary tower has alarms and our engineers are attending to the problem. Come Monday morning, after 2 to 3 days of being unable to watch my movies and channels , voila all problems solved. It is beyond frustrating!!!!! Do they have a critical bill to pay before a certain date this time of the month and then can't? Or are their employees not working over weekends? Or are they implementing/upgrading systems untested and then fix their errors for a whole weekend while the customer has no internet?
