The first paragraph reads...
Broadband provider Plusnet has blamed a “system error” after a switch of payment providers resulted in the ISP failing to collect the January 2019 payments from a small number of their mobile customers. The issue was corrected but some of those hit discovered that their credit files had been given a negative mark.
The second paragraph which you quoted seeks to conflate this issue (mobile phones) with the new billing system (broadband and land lines) which are not the same.
The third paragraph returns to the mobile phone billing issue..
According to MSE, the negative marks were present on credit files from March until late May 2019 but have now been resolved. The ISP has not contacted
Note that the 'blog' continues to muddy the water by referring to "ISP" where as in context it should have read "Mobile Phone Provider".
Reading further on you'll see that the comment from Plusnet refers to MOBILE PHONE users.
Hence my suggestion that the first link doe not have any real relevance to the discussion of broadband billing … and issues arising where the account holder does not have the funds to cover the automated payment.
Superusers are not staff, but they do have a direct line of communication into the business in order to raise issues, concerns and feedback from the community.
