Incorrect amount payed in my account

I'm very disappointed at a service I received from old mutual regarding investment claim.. On Monday 18 06 2018 I went orange farm branch to submit a claim on my investment account of which I got good service,then I had to wait 5 days for my application to be processed for an amount of R 1097 which I signed for .00 but this morning I got a notification for an amount of R10.97 deposited in my account from old mutual how does one make such a mistake, how do I continue trusting old mutual with my life policies if this is what happens when I claim.. Is this what my family and I will experience also when claiming from my life policies what happened to R1080.00 difference that was supposed to played into my account. I have been contributing on this investment since 2016 now that I need the cash I get a slap on my face instead.
