No feedback at all

Ive app**** for a credit card with nedbank and on 01/01/16 I got an sms saying my card has been approved. Eversince then no one contacted me. Yesterday i called and logged a complaint with them. I was told someone will contact me and that I should get an sms with a ref nr for my complaint. Recieved no ref + no phone call yet. Its really frustrating when you deal with banks that dont value u as a client
