Worst customer service and scam charges

Has anyone ever dealt with Tejaswini? The only response I received were very generic. This person did not answer any of my questions directly and answered with wrong statements. The person said that I was informed about the charge by the tech? Really? I didn’t know that employees are compulsive liars at this company! I signed up for the internet service. When we tried to set it up I called and informed the employee that the internet isn’t working. The tech came out and fixed it since something has to be adjusted on the outside connections. On my bill I saw a $100 charge for an installation fee. This is such a scam. Nowhere did I sign or agree to anything. The employee at the phone or the tech did not disclose anything either! Cox is the worst provider ever and a scam! Unfortunately, there are no other options in this area because I would cancel immediately!
