Discovery Bank's card delivery service is hopeless!

I ordered a new credit card more than two months ago, and I'm still waiting for delivery. Contacting the bank is not easy, as their systems are sometimes "down", and their face-recognition system is troublesome. If one is lucky enough to get through to the call centre, the staff are very charming, but I am still waiting for my card. Issues have been - (a) the delivery department was trtying to use anaddress that I had left 7 years ago (and since then I've received a new card at my new address, buit they still tried my old address!); (b) they have twice had wrong cell numbers for me; and (c) their delivery people do not respond to calls or email respoinses. I have lost all confidence in Discovery, and am seeking a new bank.
