Payment I Made has been added to my next bill?

[#1]

Hello there,
I'm having some issues here as shown below.

Bill date : 22/12/2018 - outstanding balance was £45.90, this was paid on 07/01/2019.

Since this was already paid why exactly has it been added to my current outstanding balance which now makes my bill for THIS month £91.13.

Bill Date : 22/01/2019

Current Outstanding Balance £91.13
Charges brought forward : £45.90 (Payment i made on 07/01/2019)..

Would someone care to explain why i'm being charged a fee i have already paid? This isn't right at all. I would appreciate if someone could look into this and resolve the matter.

Hi there @mrj1992

I am sorry for any confusion with your bill, I have explained the breakdown and the charges further here for you (I have added this to the account due to it containing account specific information).

I hope this helps, but please get back to us if you have any further questions with regards to this.

Congratulations, you lost yourself a customer who was with you for over a year because you tried to rip me off.

Wonderful service.
