Can't trust

On 24Oct I app**** online for a CC and within minutes a consultant called me. By 25Oct an offer was made that I felt was very low and I declined based on the low credit limit and a R100 monthly fee. The consultant then said but you still get to use the travel lounge when you travel lounge benefit, as you are still traveling in Dec. By 6 Nov someone calls to explain the rewards and I need to spend R20k to activate this benefit. I logged a complaint on 6 Nov and then today I hear it takes upto 21 days for someone to respond. I would never have signed up and I feel that I was given false info. Application Sign up turnaround time minutes and complaints 21 days. Where is the balance. Definitely closing my Discovery Bank account on 25 Nov. I can't trust this bank.
