Poor Service with Zero Communication

I have written used the contact us page 3 times just to have no one respond. I have also contacted the call center where I was told someone would be in contact but no one ever bother getting back to me. The issue which has been raised has been defined below:

I see that you guys have implemented hourly reading of water which was working fine until the 7th of July @ 18:00 where I stopped being charged for water based on my usage at this date/timestamp. Please advise as to when the water billing for period 7th July @ 18:00 to Date will be billed to my account? Please can you also advise on roughly how much I am expected to be billed in order for me to ensure there is sufficient funds in my account.

I have also previously asked if the best way to download my transaction history since the 1st of October into an excel file. Please can you liaise with your IT team to raise a change request to make the download to excel option for a date range possible for your clients. Alternately, please can you e-mail me full transaction history since the 1st of October 2019 in excel format?

Kindly advise soonest.

Thanks.
