*****ULANT TRAANSACTIONS ON RCS CARD

My husband has a RCS card which was use once for an emergency.. On 25 October, I received a call from a call centre number, a lady who claimed to be from RCS. She told me that there were *****ulent transactions on our card and I will receive a "number" which mean that the card will be cancelled. After personal investigation, the number from where the first call came from, was diverted to a cell phone number which belong to another person (with no answer) About 20min after that call, I received another call from a RCS agent... very co-incidence.. She told me that the previous call was also a *****ulent call and that she will forward a form to complete about the transactions. We have done as requested... We received notification that we will be liable for the R4 000 transaction ..I requested detail of the R4 000 transaction: Item purchased / At what store was it purchased / Contact person and delivery address where the item was delivered (as they stated it was an online purchase) I Also wanted to know how a stranger could gain access to our card and account details, as the card is with my husband and he used it once and never again.. I spoke to Emithle on Friday who claimed that she could not give me any information regarding the purchase details... She firstly wanted to verify my husband from A-Z before speaking to me - Why not provide details to him about a transaction on HIS CARD??... Why did the previous consultant spoke to me regarding the *****ulent transaction and forwarded the form to us if they firstly should have do verification... How did they in the first place knew that there were ***** on the card and co-incidentally called me just 20min after the first call if the first call was *****ulent?? My husband also gave instruction a few months ago on the telephone when we reset a pin on the card.. WHY was the number not changed??? How can they held us liable if we cannot get any answers on our queries??? Email from where I received the form to complete: EM_CARDS_CO_BRANDED_ENQUERIES <***>
