Read the first section atop page 2 to see how often the meter should be read! Not very tight, is it.
At the least you should be demanding a written/emailed explanation of why they state your meter cannot be read, but recognise that the system is based on quarters not months and you appear not to have ‘missed’ 2 quarters yet with 5 estimated monthly bills.
Regardless, when you have it sorted you might not get better meter reading services through another retailer, but maybe you can pay less for the privilege of being done over and get more competent customer services.
This thread might also be interesting for you.
