No Assistance

I sent an email requesting a credit limit increase on the 19th of March 2016 and there was no response. I called on the 22nd of March to follow up and I was told I need to resend the documents to another email address. On the 29th I called to follow up and spoke to different people because they were making me hold for over 15 minutes but still I was not assisted. I then called today (30 March) and spoke to different people as well and still I haven't received any assistance and looks like the call center doesn't even know what they are doing cause I've been given 2 different email addresses to send my documents to: [Email Removed] and [Email Removed] Please assist as no one is willing to assist. As you can see its been over 10 days and its supposed to take 48HRS.
