Discovery Bablnk shocking service.

I signed up for Discovery Bank. The sign up process was effortless. I was due to receive my new bank card but it was ****** in a hijacking of the courier van. It's now 6 weeks and to date i still have not received my replacement card. I have contact Discovery bank about 20 times to sort this out from their call centre to the ***** department. I have been to see them at their offices in Sandton. All my efforts and zero service. I have threatened to cancel all my Discovery products but still no response from any department at Discovery.
