They have no clue

Phoned ABSA's call centre to ask them not to mail the accounts of people who no longer live at my address. The couple also happen to have accounts with another bank, which I phoned first to do the same thing.That bank helped amazingly, though they could not change the couple's address without their permission, they could stop the mail coming to that address.Not so with ABSA.After the consultant left me for about 8 minutes to consult with a guy called Newton, he said they can't do anything about it, I must phone the couple and ask them to come in, as though it is my responsibility and not ABSA 's to maintain the correct information on their clients. Even so, I told the consultant that it is impossible for me to do so- the couple obviously moved, their mail has been coming to my address for several years.I don't know who they are or where they are. I told him that the other bank managed to take my address of their mailing list, why can't ABSA?He left me again for 4 minutes and came back to tell me that I have to come in to the branch to sort it out. I informed him that I don't stay in Joburg, yet he told me it's the only way.If the other banks could do it, why not ABSA??
