credit profile affected by credit card that was never collected

after many attempts of calling and confirming that i dont want their credit card i am still receiving sms's stating that im in arrears with the credit card account. the card as never been collected or activated so i dont know how fees can be billed on the account???? this has had an impact on my perfect credit score which i would like to be reinstated. this is ********* conduct towards customers and i need it dealt with ASAP. This matter has also been escalated to the Ombudsman
