Fidelity Investments complaint: Check on time

I switched banks to help with bills and rent I thought I would get it two days earlier did not know fidelity was not a bank and don’t do two days early. I have had to call every month because my ssdo check was not in there on the day it was expected I would get a response..when we get your check it will be deposited and they won’t get the check til the first I called ssa they said they don’t hand out checks early it’s up to the bank to give it to me I called over and over to sss and was told the same my credit won’t go up my rent has been late more time than it should have and fidelity says you should get another bank or hang up on me or say when we get your check we will deposit it every time that was said they don’t get it early I called now again this month late. Last month I received it in the 28th month before the 30th only twice I got it on time In 7 months.
