Advice Please

Hi, new to this so please bear with me.

I had an endowment with Scottish Widows mature last month, nothing special in that or the fact that it was way below original forecasts. However, when they wrote to me asking me to call them to arrange where to pay the money, it became complicated.

Cutting a long story very short, when I rang them I asked what the maturity value would be they advised that they wouldn’t know until the ex@ct date. So I asked whether if I took the last declared value and added the relevant terminal bonus rate they had declared in their 2018 press release I would get a good approximation of the value. I was advised that this would indeed provide a good estimate of the maturity value.

Unfortunately when the policy matured it was close £4K less than the figure I had calculated. SW were unable to answer my questions so ultimately I made a formal complaint which they have upheld. They have offered compensation of £175 which they say compensates me for any financial inconvenience ! I am not so sure, should I accept their offer or are they really “in the wrong” and I should insist on a significantly higher offer ?

Views and opinions would be very welcome.
