Memorial Benefit unpaid

On the 12th of July 2020 my mother passed away. During the time of claiming I got paid her funeral payout and was promised by Hollard that after a year I would be paid a Memorial Benefit, they gave me an amount I was going to receive. After a year I started contacting them, trying to get my late mother's memorial benefit as promised last year.

Upto this point they have not yet paid me, despite the many phone calls and emails I have sent them. Instead they make more promises that I would get the money in "2 days", on some instances they asked me to send them my bank statement so that they can confirm if I haven't received the payment yet, because according to them I am supposed to have gotten the money. All my airtime is finished talking to these people for months. Kindly intervene
