I am very disappointed at the service I am receiving at Rcs group I paid my Makro credit card on the 02/09/2023 with EFT and I have been harassed with threatening calls to pay my account of which i told them I have paid I even send them proof of payment on the 12,what is said I spoke with this woman to explain the story with my office never at 09h09 she kept me holding for like 30 minutes and told my payment is nor reflecting I must wait for 48 hours after sending an Email I told her I have sent proof of payment on the 12 th already she shouted at me and when I asked her not to shout she hang up the phone on me what kind of pathetic service is that
