Approved Credit Facility without contacting me

On the 23th of October I received an SMS from HomeChoice stating i have been approved for credit and after that, a follow up SMS confirming that my cellphone was changed.

I have no idea and have not app**** for any credit from Home Choice, i have been trying to contact them on *** for customer service but the number disconnects when i select option 2 and i have sent an email to ***, there is one responding to me.

I am trying to figure out how can they open an account in my name without them confirming with me first. i have been exposed, someone is applying for credit in my name.

I want this credit facility closed and investigation done, because how can they approve the facility and notify me afterwards without contacting me before the application.
