Pathetic service by OTP contact centre

I have been struggling to make online payments using my phone due to Absa not issuing OTP numbers. I contacted *** and was told to visit my nearest branch to have it fixed. I went to Absa Glenfair and was informed they can not help me with the service and that I was supposed to be assisted telephonically by the very OTP contact centre I had contacted prior to visiting the branch (number mentioned above). Absa glenfair contacted the OTP centre and Sibongile advised that I should disable my wifi and rather use mobile data to make payments. She assured me that once I start using mobile data then I would be in a position to start making payments again. I have switched to mobile data for online payments and I still don't get OTP's. The OTP center is also difficult to reach telephonically. You will be placed on the line for more than 30 minutes. I am tired of being sent from pillar to post and ready to close my account with Absa.
