What do I NOT like about this business...EVERYTHIN...

What do I NOT like about this business...EVERYTHING! Optimum is the worst company ever. Their customer service wait times (on hold) are beyond comprehension - I was on hold for a total of 1 hour and 45 minutes and spoke to 4 different people, all of whom were useless. I have been charged repeatedly for a service I had canceled (and I returned the equipment in person) yet, they have no record of any of it and no one seemed to care or know how to recify the situation. I finally got someone who "assures me" the service has been removed from my bill. Meanwhile, I need to jump through hoops to get my money refunded. As long as they are the only game in town - nothing will really change.
