Payment failed - cannot make late payment on online payment system

[#1]

My most recent direct debit payment (29/01/2019) failed, as I did not have enough funds in the relevant account at the time. I am trying to make the late payment today using the online payment system (https://www.plus.net/pay) but it is not working for me. I want to get the bill paid as soon as possible without my service being restricted. 

Is there some other way I can pay this bill? When I called I was on hold for quite a long time, so it was not viable to remain on the line during my work day.

Hello @Mcginljo,

Thanks for getting in touch.

I am very sorry to hear you are having trouble with making a payment and I apologise for the inconvenience caused.

I have checked over your account and it seems yours has been affected by a teething issue originating from our billing upgrade. I have passed your information along to our incident management team to roll a fix out on the account once created.

Thank you.
