Poor customer service

I have NEVER experienced such poor service from a bank. After phoning Customer Service from the UAE to change the method of receiving OTP's, the consultant tells me I can't receive OTP's other than via sms so I will have to switch on my roaming. How is this practical? The previous consultant told me I can receive OTP's via email, now suddenly I can't. The next lady I talk to tells me that I should find someone who is in SA who I trust, then change the number linked to my OTP verifications to their number and then everytime I do a transaction, I should ask that person for the OTP. ABSA, how is this professional? And then I ask if she can advise on how to transfer all my business to a different bank, she drops the line. What a poor representation of the staff, quality of training of staff and service provided to customers.
