Foschini not willing to assist

I received a SMS two month ago informing me about money owed to my Foschini account. I immediately contacted Foschini accounts department to dispute expenditure because I did not make any purchase. I was informed that vouchers were purchased online using my details and vouchers invoices were forwarded to me to open a case. I have been to police stations more than five times and police are refusing to open a case. The police want Foschini to open case since the ***** was committed on their online system without my involvement. Additionally, I did an affidavit disputing the expenditure against my account and Foschini refused to accept it without a case number. I have now received a SMS informing me that I have been handed over for non-payment. I’m extremely angry with the way Foschini has handled my case.
