3 Weeks Chasing RSA Retail Savings Bonds My Money

I have submitted a request for withdrawal over three weeks ago and to this date nothing has been done to process my funds. It’s very disappointing that I cannot access my own money from this institution. I have made multiple phone call, sent emails and even went into their office or branch where I was told someone would call me into days, almost a week later and still nothing. No response or feedback to my request to have this matter resolved. The administration and systems they have are really bad. I regret investing my money there.
