I went to ATM to try and withdraw it said invalid pin I went to pep again they send pin again, still it doesnt work i went for the for thr third time they keep on reseting same pin while its invalid, for the fourth time they said their expriencing network problem they will call me. the following day on 21 August 2018 they called me and asked if the matter has been resolved i said no, She said she will call again. I never heard from them even today. I want to closed my Pep Bank Account with them and i need my R200 refund that I transfer with immediately effect.
