Tymebank Incompetence!

My simple question to Tymebank; - "I am not receiving OTP's for checkers online transactions, I am receiving for all other online transactions, can you please check if an otp was sent to me?" In a nutshell, I have made more than 10 calls to Tymebank, they have admitted on truecaller recording more that 6 times that the OTP was never sent from Tymebank. All the call centre assistants cannot tell me WHY? They refer me to Vodacom and to Checkers and in 10 phonecalls with more than R200 airtime wasted they cannot understand the simple question! WHY did you not sent me the OTP! What is wrong with this picture, am I speaking to robots that can only read scripts and have no clue about what the question was! Today after 10 calls R200 airtime wasted and after 7 days they are not able to help me! I am still not receiving OTP's for checkers! This is the worst experience of incompetence that I have ever seen in my lifetime! PLEASE PEOPLE THINK BEFORE OPENING A TYME BANK ACCOUNT! (Karien Hollister ***)
