Totally unacceptable

i put a call to the ABSA ***** line after I received an error on the ABSA Internet website that they had detected a sim swap on my account. After confirming my details with Eugene he proceeded to tell me it had been sorted out I need to just log out and back in again. I asked him what has been going on with ABSA as this was the second time this week that I've had to contact them about an error. the other time my credit card was deleted from ABSA's system and I had to take time off to go to a branch and sort it out. Eugene then told me it was an error in my network, that the network detected a sim swap or that I could have put my sim in another phone. After I told him that this was not the case and obviously I wanted an explanation he then told me it was error on my network. When I told it was not possible, as my network did not change, he then cut me short and asked me if there was anything else he could help me with, without even tried to explain what had happened. I was totally furious as I had been waiting for over 20min on the line to fix an error caused once again by ABSA 's network. its not only acceptable. but its also very inconvenient when you trying to run a business
