Worst experience ever

This has been the worst experience that i have ever received. i've been struggling to login to the AF Connect site to view my benefit statement, i'm unable to receive the OTP pin on my cell to login, i've contacted the Alex Forbes contact centre, and they keep on updating the wrong details on my profile, its been 3 weeks later and 4 phone calls later with their call centre agents, yet they just cant seem to update my email address and cell phone number to the correct details that i provide to them on the phone, i'm not sure if they are trying to prank me by getting it wrong, how do you get the cell phone number and email address wrong each time, then i have to wait 2 days everytime to test it after they update it, this has been the worst experience i've had with a call centre, i thought City Power was bad, but the Alex Forbes call centre has taken it to another level.
