Rude and Unproffesional

How many times do I have to send my proof of payment to tenacity. All I get is a phone call employee puts the phone in my hear for no reason and send an sms my payment was not made (and boy is she rude, cant even hear he name). On the proof of payment is the correct amount and my membership number to make it easier to locate my payment. I made Two payment this month. Why do paying client have to go through all this rude and unproffessional treatment. ACKERMANS I AM CANCELLING BECAUSE OF THEM. PLEASE SENT THE BALANCE FOR ME TO SETTLE ACCOUNT.
