GAS INSTILLATION

This is the worst service ever in my life. Most *********** with false promises. They give a date when doing a purchase at Macro to do the gas instillation but, just to give another date, call and say the system made a mistake unknown to them and say the first date still remain, then calls and say the installer is sick, SORRY we cannot do your gas instillation?? PATHETIC EXCUSES + SERVICES!!!!
