Cancellation Request Due To Terrible Service

A zero rating should be considered for this service provider! After years of service where NONE of my contracted items could be fixed and applianes were actually damaged, I realised that using Mastercare was of no benefit to me as I had to keep buying new appliances. They would always, after the fact, advise me of the cost vs cover until February 2020 being my final straw when they pitched this to me over repairs to a washing machine. I advised the office I wanted to cancel any relationship with them. This was not done. On the 14/07/20 I sent through a cancellation email to the contact info listed on their site. I have not received a confirmation. I sent a follow up on the 27/07/20 and again no acknowledgement from the email address on their site. I have sent a follow up again this morning after the 6th month of a debit order Mastercare never stops despite the ****ty service and my wish to cancel. When will I receive confirmation of cancellation?
