I called on my landline, which I had just used to to make another business call with no problems. The woman who answered my call around 3:25 pm on Tuesday April 27th told me they could not hear me and started saying la la la la la, can t hear you! like a child. I waited an hour to be mocked on the phone by a grown woman who works for a company that provides a service that I pay for. I will be switching the second I can.
