Duplicte billing

Battling to resolve a query of duplicate accounting. I am being billed twice for the same premises on accounts SOL00707 and TOTO00033 Tried the call centre but they didn't get back to me. Sent emails to the general email address - Ticket EACA79A5B889F (13th September) - no response.

Tried emailing the credit controller for the account but the email not going through.

Need to have this resolved and get a refund for the TOT00033 account.

Thanks
