RCS Credit Card application delays

On the 31st of Jan i was provisionally approved for a card of which my proof of income was requested.I sent my 3 mths bank statement and received a call telling me that they only see 1 salary upon which i aent my 3 mths statement again and advised that i am weekly paid...was then called and asked what my salary deposit references are on my bank statement, i advised the consultant this on Wednesday 05 Feb and was tols to wait until i receive a call again...today i received an sms...stating that money credit card has tried contacting me to finalize my application and that i should call ***.I called the number and the consultant asked for my ID number,after goving her this she called me on my full name and then said they are waiting for me to send my proof of income,i advised the lady that tjis was sent already and that another consultant had requested my salary deposit ref in the week therefore they surely have the statement.The consultant then advised to call back tomorrow as the system is offline.My problem...if system was offline...why did she manage to find me with my ID number ...if aystem was offline...why sms me to tell me that they have tried contacting me and i should contact to finalize my application...this consultant also insulted me by calling me mam because of my voice.I felt she probably thought that it wasnt me but then she could have asked aecurity questions to confirm this as you cannot decide how a customer should sound...and why does it take so long to complete the application
