Shocking service form Standard bank credit card division

I cannot use my c/card for online purchases sine Thursday 1th April. I have spent 4 hours on the phone. Have sent 10 emails. Have received false information and have been refused to be given the contact information of a more senior person. I have been insulted and treated as a fool; Do you know how to make an online purchase? If you were told on Thursday there is no problem with ccard, then there is no problem! Forced to phone 2 suppliers to find out if the problem is on their side! Told to try a different browser! Had to ask a family member to make an urgent payment to valu of R49000, which I have lost out on ucount points Have lost a great deal on a sale item that I wanted to purchase online as this has expired Feeling - Desperate, frustrated, undervalued and cheated. I owe no money on my card. I have an excellent credit rating. I have more than R100000.00 limit available.
