Bad Customer Service Received

I previously owned a rain account which was last used in 2021,I recently tried making payment to a new Rain account and incorrectly paid the old one. This payment was made on the 2nd of May and I have called them numerous times to log this dispute. Each time I would call advising the person of the dispute and advising them that I am following up, each would then advise that there is no active/open dispute at this time for my call. Up till now I have received no outcome and my funds are gone. Not good service at all I am even considering cancelling my current subscription with them as this ordeal has left a bitter feeling towards them.
