Promotion adverti*****t from DirectAxis in partner with FNB

I recieved a email from DirectAxis dated 16 March 2021. In the email they offered me a promo which I can switch to FNB bank and choose between 4 different sign up gives. I have signed up following instructions from the email. I have phened the number provided on the bottom of the email which is the number of FNB bank. I have phoned but no one can assist me they transfer my call from one department to another no one can give me details about the promo. The same with directAxis I have phoned them and they also cannot assist they told me they will phone me back and a week later I have not recieved a phone call from them. I even went to my local FNB bank and they advised me to phone DirectAxis because they don't want to do the swithing of bank and then there is no promo and I do not get to choose which sign-up give I prefer. This is totally unacceptable for me how can you send a email advertising a promo but no o E can assist otlr phone me back. This is verry unprofessional service and DirectAcxis is making me to believe that FNB has no service as well!!!
