My telephond at home was not working . I had an error on my phone stating " check Tel Line". I called optimum after so much trouble shoot and attempts they Schedule a technician to my home. The Technician arrived on the morning of Friday. July 23rd . He checked the phone line and the electrical panel. Finally he told me it may be a problem with the phone line but optimum no longer trouble shoot phone lines and everything is now remote. He suggested I will have to call an electrician or I can plug my main phone into a moderm which I have . I got a bill for 80 dollars stating the Technician claims he did some wiring which is not true. He did nothing, no wiring. I cannot pay for service that was not rendered to me. This not right and I will like a through investigation and the service fee credited back to me . Thank you Gloria
