Links wrong cellphone nr to credit card with inability to fix

Poorest banking service. Links wrong cell numbers to credit cards and then for months have the inability to rectify despite several phone calls and emails. I am highly disappointed for making use of Discovery's Bank. My wife's cell number is connected to my credit card and my number to her credit card. With every phone call to Discovery to rectify this, more promesis and no results. I cannot be with my wife every time I try to make an online request/purchase. I am utterly disappointed in this service and do not recommend a bank like this. If you make a mistake rectify it, but keeping it like this for months on end is just rediculous.
