Not good business practices.
I had a subscription for the Termly.io service. I received an email that Termly was unable to process my payment for the upcoming year. I notified them that I was not renewing my service and had cancelled my subscription. I requested they not keep trying to process payments and to stop. I continued to receive emails that they could not process the payments and they requested I update my payment information. Communicating with this company has been extremely frustrating. I refuse to pay for another year of their services and do not neither understand nor appreciate their extortive business practices. Stop means stop!
