RCS IS JUST PATHETIC

Ive had my account paid up for 2 years now, left it open for emergencies. I receive 3 SMS's on 7 February 2019 notifying me of purchases of R3000.00 at 12:49pm ; R1524.66 @ 12:56pm and R2500.00 @ 13:19pm while i'm at home minding my own business. I get through to the contact centre after almost being on hold for more than 45mins and request that the card be blocked and the operator tells me all the steps I need to take to resolve this matter. I follow suit and send all the necessary documents on 9 February 2019 and receive a ref No: ********** 02323. I was assured that i'd get a call back 21 days after the investigation.......to SURPISE....not one phone call, not an email, NOTHING. I have to keep calling and evertime I do, i'm told that the investigation is pending and i'll get a phone call soon!!!!!!!! its ****** 3 MONTHS Later NOW.....how long does it take you to investigate?????? Yet you are quick to want me to pay an instalment I know nothing of!!!!!!!!!! SO PATHETIC RCS!!!!!!!!!!!!!!!!
