Jerked around again

Cox Internet scheduled a day to come install. Told me someone 18+ had to be at location to receive service. I took the day off to meet contractor for Cox. The contractor showed up but said he couldn't do service without a 2nd person or couod I help him. So I choose to help him. But he still could not install. The Cox rescheduled the install for today. I couldn't take off again so I asked my mother to drive 20 minutes to my house to be there for the contractor.  A different contractor shows up, and I was told that he could not install internet today. Another wasted day. Then I called Cox support to find out whats going on. I was told that the contractor had the same issue as the previous one sent to my house. Sierra, the customer service rep, was condescending and wouldn't answer why dod Cox send out another contractor that couldn't do the job? Twice having to have someone be at my house for service to be done. Sierra wouldnt answer me. Instead, she would pause on phone for a period of time with me saying, "Hello, are you there?". 

This was a costly and aggravating experience.
