DISCOVERY BANK - NO ASSISTANCE - NO COMMUNICATION

The bank advertises 24-hour assistance for creditcard users. This is however useless. They could not assist me on Saturday (2 October 2021) evening to do a payment with my credit card, I am today 6 October still waiting for assistance as a problem was logged. Yesterday I requested a call back to sort this problem, BUT still no service. This lack of service will definitely not be acknowledged in their advert to change to their new way of banking. This ordeal kept me on the line for more than 30 minutes
