Did they pay my taxes?

This complaint is against Metropolitan life Botswana. I had two claims, one death claim and then my own policy that had matured. My values on these policies were given by memo email style, stated the taxes that had to be paid, the funds were transferred into my account, but a year later, I have still not received any formal document stating the values, (numerous email requests) neither have I received a tax certificate for the tax deducted. Emails remain un-answered, waiting for the tax certificate, which I requested assistance with from the helpline, since March 25. I cannot file my personal taxes due to this outstanding certificate.
