Mercantile Bank system UNSTABLE! No escalation process!

Worst BUSINESS bank in SA!! First I open an account where they send me the documentation to be signed over the "Docusign" app via e-mail, where you click on it and then it sends a token code to your mobile number, got that all signed etc. Then I wait almost two weeks for my bank card to be delivered "BTW you do not even get notified that you are even going to get a card" Secondly I call the card activation line after receiving my card, just to find out that my e-mail and mobile number (that was used successfully to open the account) are not existing on their system. Therefore I fail to answer the security questions to activate the card. Escalated this x4 times but no one can correct it. So I get a lady's name and call in and ask to speak to this lady. She called me back and got the issue resolved in a week "then only I could activate my card" Now you need to call in again to activate the OTP "Online purchase" otherwise you can not purchase anything online!! Different department that activates this so you must wait "waited 2 days" where I called them again just to find out yes it has been activated now. Guess what!!!!! Still not getting a OTP pin to confirm purchases online, two other service providers can not get my card uploaded on their sites for automatic payments. Called the customer care center at 086 030 925 that referred me to *** to escalate my situation. Guess what!!!!! The call keeps dropping and when you get through they put me through to someone and then the call dies the whole time!!! Called from a Vodacom number and MTN number so it is not my line. NOT a BUSINESS bank at ALL!!!!!!!
