Impossible to change OTP Number

Having a Discovery Card has many incredible perks, but customer service may be lacking.

I have been trying to change the cellphone number for my OTP for purchases for almost 3 months with no success.

I've called the number on the website, was told they'll call me back within a week. After a week, I finally get called and have to go through numerous security questions. The gentleman tells me he'll make the changes.

OTP still goes to my old number.

I call again and go through the whole procedure again. I then get told because the card is held by FNB, get sent to FNB, then redirected to numerous voice prompts and somehow end up at the wrong card department.

Your website tell me that I have to call in for security reasons, and while I understand this... it would be great if phoning in actually yielded results instead of wasting 30min being passed from department to department.

I am now carrying around 2 phones so my OTP is available to me.

When I don't have my OTP number, I default to my other credit card because the inconvenience caused by Discovery is infuriating.
