Early days bad experience

I have just opened a business account with FNB not because I am unhappy with my current bank, but because their systems are slower in verification response, so I was taken by the services of online account opening. So I went to a branch at Eastgate to submit all the required documentation, now the only thing left was for me to get the card then I will be ready to go. Yesterday, I received instead two cards of the same nature, which I could not get an answer from the courier as to what the other card was for. He then told me I did not need to go to the branch to have them activated as he was already doing that via his devise, that is sending a confirmation message to the bank that cards are received. To my surprise when I tried registering for online banking, I could not come right as it said the card is not active. I then loaded airtime to call the number that appears on the attached letter (that came with the card), the consultant I spoke to could not help me either nor take ownership of my request to have card activated, but said I should go to branch. Another challenge is that a week ago, I sent an email requesting them to correct my cell number, which I have no response to date
