Concerned Investor

After reading reviews on Hello Peter, I wonder if I should continue investing with Rsa Retail Savings Bonds. Many companies have invested with National Treasury but I've lost confidence. Based on reviews, I'm not sure if I'll ever see my hard earned money. I have had my fair share of poor services. My investment is left with 16 months before maturity. I'm yet to find out if I'll get my life savings back. This is very concerning.
