Fedhealth deaf and ingnorant

My wife had a policy with these people for several years. owing to the Covid outbreak she lost her form, of employment and had to cancel. Now every single month they attempt to put the debit order through causing her untold problems at the bank and with her credit rating. I have writted 7 e-mails to them and still they ignore us. She will now be forced to go to the bank, queue once again, and this time change her account details. Surely there should be a law against their ******* practices to protect the consumer. Beware with these people they do not give a damn.
