I went to Ackermans in Pretoria (Sammy Marks) and my card expired, then they called the contact center and l was assisted by Litheli and she send me the QPC number that they are supposed to use, and it didn't go through then we had to call again and got through to BARRY, where s/he made notes that l have failed the security questions which she never told me about but all she could do is just hang up the fone in my ears while speaking to her, had to call again where l got to understand that she she made notes that l failed security questions, now my card has been blocked and l could not receive the card, may l kindly ask a Manager to contact me so that we can get this matter resolved, lm very unhappy with the service that l have received from Ackermans contact center,
