Real watertight fortresses, impossible to do anything over the internet, I just want my last 3 payments in the last week that I've been trying, if the calls are all busy, or they hang up on you.
How to fix this problem.
I see responses from the employees of the carsat south-east its makes me want to vomit, that lies unable to tell you the truth, there is nothing that works, or they purposely do not want to answer retirees , and the future.
For 1 week I have been trying to get my last 3 payment advices, impossible by internet, the phone is not even worth talking about.
I need an assistant from the carsat southeast since July 1, 2019 to date.
So either you change jobs or let the professionals do their jobs.
