Insecure Cards and Utility Bills that aren't acceptable

My wife and I essentially manage a “joint” FNB bank account, albeit that the account is in my wife’s name. On Sunday (20 Nov) my wife and I went to FNB, Cresta branch, to request that I have signing powers on the account and that I too can be issued with a debit card for the account. We are still trying to get our head around what happened thereafter, but suffice to say we are not impressed. Firstly: despite our desire to keep to the task at hand (per above), the consultant (Lesego Sehume), seemed more intent on wanting to transfer a significant portion of funds from the easy account to a “7-day call” account. The reason given was for security of funds. Ms Sehume did a very sales job that bordered on “fear ****” i.e. her sales pitch came across as some like a disability insurance sales person i.e. if you don’t do this insurance you might lose a leg in an accident and then what are you going to do if you not covered. To this end we are now completely beside ourselves because based on Ms Sehume observations my wife and I now think that FNB’s debit card IS NOT SAFE, and that exiting security measures in place, like daily limits etc., ARE QUITE INEFFECTIVE. Please can FNB answer if this the case (capitalized points)? Also, to effect the changes requested on the account we were asked to bring in a document for proof of residence. Having recently purchased a property (which the Bank can see from the transfer of funds from the account) and having supp**** proof of residence documentation to the Conveyancing Attorney, we thought that this same proof of residence information would suffice. In this regard the documents made available to the Bank included: a fully constituted statement of account from SARS with personal tax number and physical address; a fully constituted statement of my monthly utility bill issued by the managing agent at the Complex where I reside; a copy in part of my lease agreement for my current residential address. And in addition to this my green ID book and drivers licence. Staggeringly none of these documents were acceptable to the Bank. Ms Sehume informed us that the Utility Bill was a “tax invoice” and according unacceptable. This is strange because if Ms Sehume happens to look at ANY utility bill issued by the City of Johannesburg they ALL include the words “tax invoice” near the top left hand corner. After informing Ms Sehume and the acting manager on duty that this was coming across as completely daft I was requested to provide them with a complete copy of the lease agreement, which I did. So at the end of the day, we feel FNB have notified us that our debit card is a very insecure form of conducting transactions and get easily confused about a utility bill that was requested. We’re not impressed.
