Bad service Discovery

I reported ***** on my Discovery Card on 1 April 2020. The card was stopped immediately and I was told 3-4 working days turnover. I than phoned four days later and was told it was a 4 - 6 day turnover! Was promised it would be “escalated “ I phoned on 11 April and again this morning 14 April was told would be “ escalated” this i cannot shop for the essentials. I need to purchase items for myself and my elderly mother on which get a good discount! No card no discount and cannot shop. Two of the consultants have been helpful and courteous however Discovery this is shocking service and totally unacceptable. It has cost be a fortune in cell calls and to add insult to injury I see on your app you are going to charge me a R199 delivery fee! Would it not be great if you lived up to your adverti*****t promises - of great service!
