New Sales department dont assist

I app**** for a credit card online, the online application went smoothly and I was approved after 10 minutes.2 days after the approval, I phoned the sales teams to find out the status of my application so that I can finalize my agreement. The sales team don't pick up their phone, I was on the phone for 1 hour and they don't pick up. Don't waste time applying for credit rather choose another bank
