Cards canceled without any communication!!!!

My bank card expires next month, so me being a good client who hates hassles I decide to go order a new card and I end up even upgrading my bank account.... Im told my card will be delivered in the few days. I wait... And wait and eventually get the sms to go collect my cards. When I get at the branch I discover that they delivered the incorrect cards... The consult advises me that she'll order new cards for and they would hopefully be delivered by Friday and I should once again wait for the sms. Saturday I decide to go do my groceries and when I'm supposed to pay.... My card has been canceled. No communication sent whatsoever....now with a trolley full of groceries and having in an extremely long Q, embarrassed.... I have to get out of the Q and figure out How to way to get cash... I go on the app to use the send imali option and the most I can send to myself is only a R1000. I try to call the call center... And I end up holding for close to 20 minutes. WOW! After almost 10 years using the same bank and yet I get such horrible service? I can't even go to the bank during the week as I'm working... And now I couldn't even do anything on the busiest weekend! I've honestly just about had it with nedbank.... Being loyal to a bank is a total waste of your time... Especially when they don't even care about their customers!!!
