Gas Meter - Complete Wrong Estimates and Massive Staement

Hi,

I have an issue with the latest gas bill received. It appears to estimate a usage far too high. On 5th November read was 0030 and the estimate for 15th is 0425, whereas the true value to date is 0055. We submitted a meter reading on the 12th but it appears to have not been processed (the electricity one was successfully submitted however).

I understand these are estimates however the difference is far to off and we would much appreciate if the bill could be re-processed since we would have far too much debit (as the reading is way off from our monthly consumption).

Are there any ways in which I can recalculate the statement to something more realistic? I am currently in debit for an unreasonable estimate.
