Absolutely pathetic service:-(

I recently opened a business banking account with Standard Bank...how I regret the day I did....it is now 2 months later an I am still trying to link my card to the app...I have contacted the call center an spoke to one of the consultants who was completly *********** of which i requested to speak to the supervisor whose name is Arnold who was just the same....he advised my query will be sorted by COB....of which it was not....this was done 2 weeks back....I called in to the call center again today an was told my query was not escalated..like ***....I have been going in circles with this bank an they just seem to not care in terms of resolving this issue...I have visited their branch an the consultants in the bank were of no help....they just put you on the phone an make u do all the work....can someone in Standard Bank do what you are paid for an fix this mess.....I have been more than patient during this time considering all that I have been going through....what else must I do to get assistance??????????
