Faulty electricity meter

Making my weekly meter reading last Saturday, I found the usage hadn’t progressed to the next thousand but had reverted to several thousand - lucky me you might say - checked it again on Sunday and the same problem. I emailed Bulb’s Help, and received a reply that the technical staff would tackle it within three days. It’s the end of the week, and nothing done or any further communication from them about what to do. Anybody and ideas or had problems with Bulb’s technical staff?
Thanks in advance rob09
