Extremely negligent service by customer by Standard Bank

As a loyal customer of Standard Bank for over twenty years as an account holder I am dismayed and appalled by the shoddy treatment I have received by Standard Bank. After immediately reporting a ********** transaction on my Standard Bank MasterCard account on the 11thDecember 2018 of R28674.00 which was effected through a phishing e-mail **** and without any valid OTP numbers, Standard Bank failed to block or reverse the transaction and are holding me liable for this amount which is completely unacceptable. The online ***** department was very delayed in their efforts to reverse the transaction and no urgency was shown in dealing with this matter which has now been referred to OBBSA the Ombudsman for banking services
