No Customer Service Contact Centre after 17H00

I had an incident last night in zevenwacht mall where i was pick pocket with my wallet this happened just after 16h00 whilst busy paying my accounts. I went to a few retail stores and i was assistant with no hassle, Foschini, Edgars my cards was blocked and i received instant replacement cards. I got to your Mr price store it was about 17:06 and asked that i should be assisted and told them what happened. To my dismay i was told immediately the contact centre are closed they close at 17H00 and they could do nothing. The 1 cashier called the other assistant both standing there. I raised the question your store closes at 19h00 how in the world can you contact centers closed at 17h00. I also asked them what happens if someone goes into one of your Mr Price stores inside the mall and buys items on my accounts they basically they just stood their mouths shut, They could not answer me. No my question is again how can you have stores that close at 19h00 even later but your customer centres are closed. Currently my card is not blocked yet and if any purchases was made on my account since yesterday after 17h00 i will not pay. Train your staff alos to deal better with customers and not just stand and cannot give answers it was very unprofessional and the worse service ever
