We moved to rural southeast Oklahoma and are severely limited in the electronic service vendors we can utilize. As a result, AT&T is the only company we can use for landline phone services (cellular signals are not accessible in our metal building home). It took a full month to get a landline installed and then nearly another full month (with 3 service calls in the interim due to a faulty "temporary" installation which consisted of AT&T running our line across a pasture and not burying the cable initially). Every encounter I have dealt with on our AT&T service has been poor – from install to billing. Their customer service line is a joke and you will stay on the phone for 30 minutes trying to resolve issues. I hate at&t and am frustrated.
