Still no contact regarding my credit card

I app**** for an online credit card 3 weeks ago. I sent the documents outstanding to the email and no body responded to me. I called and they said they dont have the documents, so I sent them again. I received no response again. I called and they said they need 3 payslips from the same company, of which i only have 2 since I had just moved companies.

I asked to speak to the manager and she said it would be no problem and she will sort it out for me and gave me a list of things to send her. I told her to please email me because I wasnt at my desk to take down her email. I think her name was sameerah or something similar. She still did not email after all I have spend complaining and begging to get this resolved. What more do I need to do? Nobody wants to help me no matter who I email or call.
