Bad service

I have been trying to get discovery bank to decrease my credit card limit since monday (1 Feb 2021). The consultant i spoke to on monday said it should be done by the end of the day but still there is nothing. I have been following up since yesterday and this is just frustrating because this a very simple request. With other banks you can even do this on the online instead of having to hold calls for long. This is very disappointing and i am starting to regret having moved my credit card to this bank.
