SMART Meter installation- issue

The Siemens engineer arrived to fit my SMART meter on time on Monday, 1st November.
He fitted the ELECTRIC meter fine, but found a problem with the GAS meter.
He explained that he would need to return with another engineer to resolve the issue and get the smart GAS meter installed.
So, I have a working ELECTRICITY smart meter, but the GAS smart meter is not yet connected.
Since the 1st November I have heard nothing from BULB or Siemens… I have emailed twice.

Has anyone else had the same problem?
