De*****ing of account

To whom it may concern. I received a call around 2.47pm today alerting of ********** activity which took place on my account on the 26th of June 2019. As I recall, the last time I used my account after a long while was on the 23rd of June 2019 at Maponya for an amount of R340, my new balance since then had been R341. My account had been de*****ed in Limpopo. Today an Edgars Active in Campus Square confirmed they spent an amount over R3747. This store couldn’t allow me complete the form as I didn’t have an affidavit. The lady from the ***** department didn’t mention this, likewise when I called Edcon immediately after being alerted. Can someone actually please explain to me what is required to have the purchase in Limpopo reversed? I can’t find time to go to a police station when it’s month end & extremely hectic at work. Besides, no one indicated that I needed an affidavit. Regards Mark
