Pathetic service FNB

Absolutely appalling service! My bank card expired on 30/4. At the end of March I received an sms stating their courier service would contact me. Last Monday, 30/4 I realized that my card was expiring that day. I contacted my branch, Cape Gate, and was told that a card had been ordered on 28th, which month I don't know!! She then told me she was putting me through to the couriers, they were experiencing high call volumes, so I never spoke to anyone. I tried calling, but to no avail! I've sent a messenger message on fb, and written on their fb page. They've asked me for contact details and said they've accelerated my query, still nothing! Surely banks can't behave in this manner? I also have a Netflix account, my payment hasn't been met this month, because of the expired card!! I'm at my wits end!!
