For starters, you are using two serial devices, both on software serial. Your Mega has four hardware serial ports, yes, four, and you are using only one of them - and that is just for the monitor. That cannot possibly be a good idea.
Your output does indeed look like mis-match in baud rate but everything seems to be at default 9600, and you only have to ensure the serial monitor or terminal is set at 9600 too.
So I know that the baud rate of the SoftwareSerial should be like 10 times higher then the one from the altSoftSerial port.
This sounds like complete nonsense, and is irrelevant anyway.
