Investment policy

I have an investment with regent insurance which have been deducting premiumsfrom bank account since late 2019. Then i found out that actually they have opened a life cover for me which i no nothing of. All i knew was that i have an investment that i took out with them. Today i called to check on my invedtment to my suprise i was told that i have 172 but i have been saving 305.76 and i asked the lady how that is when she told me i have a life cover deducting from the sane premiums. Am so angry right now and i want all my money that was taken from me
