Redis, almost no commands work properly, get Error Unknown command for KNOWN COMMANDS - redis

Question

Trying to make a SIMPLE backup of our Redis Database that is on Heroku for a Ruby on Rails command, I connect using redis-cli just fine, I can type help save and it says it is a command, but when I try to run save it gives me a lame error that says:
ec2-34-231-26-8.compute-1.amazonaws.com:19099> save
(error) ERR unknown command `save`, with args beginning with:
ec2-34-231-26-8.compute-1.amazonaws.com:19099> bgsave
(error) ERR unknown command `bgsave`, with args beginning with:
ec2-34-231-26-8.compute-1.amazonaws.com:19099>
Yet if I ask for help on these commands they do in fact exist:
ec2-34-231-26-8.compute-1.amazonaws.com:19099> help save
SAVE -
summary: Synchronously save the dataset to disk
since: 1.0.0
group: server
ec2-34-231-26-8.compute-1.amazonaws.com:19099> help bgsave
BGSAVE -
summary: Asynchronously save the dataset to disk
since: 1.0.0
group: server
ec2-34-231-26-8.compute-1.amazonaws.com:19099>
Does anyone know why Redis doesn't work properly?
It is the Heroku Hobby Dev version and I am connecting to it via Windows which is not giving me ANY trouble at all other than the Redis Server not working properly. On another instance I get an even stranger error that says Save is not allowed?
I have searched for hours and there appears to be NOTHING on this subject at all which is very confusing to me. A lot of the commands listed on redis.io return that same stupid error that the command doesn't exist when the help clearly states that it DOES exist.
Any help would be appreciated..

I hope this may help someone, In my case was that there was a rename in the configuration
check your redis.config file
I had
rename-command SAVE "SV"
now, type your rename command and that's it
127.0.0.1:6380> SV
OK
