BellSouth Allowed Someone To Sign A Contract For Me Port Orange Florida

We have two problems with BellSouth. In January of this year an outside contracted worker with BellSouth came into my business with a bill and asked my receptionist, who has no authority to sign on the business account, if she would like to change the company's service. They allowed her to sign the contract, and she has no authority to do so. We have since contacted BellSouth with no response. We have also tried to downgrade our current service in which they told us our account was frozen. In the meantime while our account was frozen they auto renewed our contract for another 3 years of service which they refused to let us opt-out of, even though we asked for proper permission to get out of our contract. They are refusing to allow us to change our service without paying a penalty for "termination fees" which we should not have to pay for because we never renewed our contract.
