Reviews of Comma antifreeze

I use comma g48 in mine. Compatible with BMW coolant and seems to work fine and is a decent price if you buy it neat.
Coolant ran out and since using this coolant (which was selected based on Halfords recommendation) the coolant has been running out weekly (with no obvious leaks) and the temperature gauge hitting the red after 10 minutes of driving. Not had any issues previously. Does using the wrong coolant cause these problems, or is there potentially something wrong with the coolant system?
