Worst service ever

I have a loan with sanlam that I had an issue with a debit going off causing my loan to go into arrears I paid across 1000 last week already I forwarded proof of payments and I get no acknowledgement I am battling to get ahold of them telephonically aswell I am just so tired of stressing if they money was received or not worst service ever and when I requested payment arrangements I was simply told sorry we cant yet I must pay more to have a roof over my head and no food because of them not even wanting to assist.
