CUSTOMER SERVICE EQUALS NIL

My Diners Club card expired on June 20th. I alerted my bank manager to this well in advance and requested that my card be replaced. It took a WHILE for a reaction from Diners Club. And then nothing despite my having forwarded all the requisite information immediately on receipt of their email. Then they send me an agreement with an old address (changed nine months ago). I request this be changed before signing. Nothing. Is this the level of incompetence that we are going to have to endure with our banking sectors in South Africa?
