Bad service and will never improve anytime soon

I am sick and tired of Sanlam and I want to cancel the retirement annuity because the service is very useless from the get go. I rep**** around April about additional the said it won’t be added as per the request, only to find out that they did what suits them they continue with additional amount I phoned earlier December to ask for a refund and stop with additional amount they refunded me but still continuing with the amount we didn’t agree of

Sanlam m sick and tired please cancel that policy and refund me fully
