10 months and counting for faulty meter to be replaced

Last September I initially complained to bulb regarding my smart meter not functioning. After sending them videos and pics it was determined the meter was faulty and had a firmware issue which needed replaced. Since then bulb have been using estimates which are in no way accurate and feel I am being excessively overcharged as I spend little time at the property in question (wishing to rent it but unable to do so because of this ongoing issue). Why is it now July the following year and I have still no date for an engineer, you installed the meter within weeks of requesting it last year. The time wasted on phone calls and emails is ridiculous and I am still being fogged off. I have had to go to the ombudsman to hopefully find a resolution to this saga as bulb are clearly incapable of doing so
