Account opened with ****** identity

Identity theft is a serious issue and one will expect companies like Foschini to act speedily when someone uses someone identity to open an account and never pay. But in my situation it looks like Foschini does not care or it does not concern them that someone used my identity to open an account at Foschini. It has been weeks now, Foschini is dragging its feet to clear my name even after a Foschini dispute form and police affidavit was submitted to Foschini and their debt collection lawyers. This is negatively affecting my credit record. Why should I be suffering because of Foschini's negligence and ignorance when opening account for their client. Do they really think that this will result in good customer experience. Foschini must act efficiently and effectively in order not to lose potential customers.
