Really poor customer service from Investec

Very poor service from Investec Had to call 3 times each time took an extended time due to “high call volumes “ Tried to phone my private banker but unavailable- I’ve never actually spoken to this person although I’ve tried to make contact a couple of times over the last two years I added my Investec card on Apple Pay to a new IPad which worked fairly well However my wife’s secondary card which was only added a few weeks ago was then removed off her phone for some reason and couldn’t be reactivated as she couldn’t be authenticated due to an email address on the Investec system which is different to hers - unclear what email address they have as this isn’t available on the app and also wasn’t an issue a few weeks ago Now the issue has been escalated to the elusive banker Really poor customer service from Investec which is supposed to provide a premium service
