IHD was working now GAS only

Initially our IHD didn’t work. Contacted bulb and they fixed it. Worked for three months or so. Then one monthly automatic reading was missed. Contacted bulb who changed communications to daily. Worked fine for a month or so. Then IHD stopped working and daily readings weren’t being collected. Contacted bulb and now we have only GAS on the IHD and only gas readings being collected.

What a shambles.

Is my editor experience common? Any ways to get it working again? Move supplier?
