Unauthorised plans on account

Opened a Miladys account last week. After collecting the card I received an sms that funeral cover and card protection plan added to my account. I tried phoning and written emails for this to be removed. Kept on for over an hour on there customer care line. Send emails with no response.

How do I get this cancelled? And If I don't pay this will affect my credit score. If I can be assisted will be highly appreciated.
