Fradulent store account

I called 3 times disputing an account that was **********ly opened with my details and they promised to send a dispute form yesterday and this morning but even now I am still waiting and every time I call them they keep on saying that they emailed it. I even sent an email to customer services but still no respond. I want my name to be cleared on ITC and the account to be cancelled immediately because they even confirmed that the details they have on they system is totally different to the ones I gave them.
