Can't get a card to work and Don't follow up

It's been over a week since my card was delivered.<br> Since then it has only worked once all other times it gets declined.<br> Note it also gets declined on online transactions where the physical card isn't involved, so it is not the card itself, it could be in how the card is loaded or linked to the account, or the account itself.<br> I have had staff members tell be because it is declined in shops it HAS to be the card and not willing to listen to anything else.<br> This complaint has been going back and forth without resolution. I have had a number of promises that I'll be called back the next day after investigation even if it is just to give a status update. This NEVER happens. Email complaints giving additional information get closed with an email that because I have spoken to someone it is assumed handled.<br> Speaking to managers Ummayah Kahn being the last one, gets a lot of promises but their follow up is just as non existent as the staff who they say need to be spoken to.<br> I am extremely dissapointed with the support that I have been getting.<br> Please before calling in response to this message could you please find out what is happening as else I'll never know.<br> <br>
