First Monthly payment taken early

[#1]

Hello, I signed up for you broadband service on 1st October 2020 and the first month's charge was taken immediately. My live date is not untill 5th November 2020. Meaning I have payed twice for broadband services this month one to plusnet and another to my current provider. Why has this happened? Please contact me to explain. Regards

Your first payment is the first month after your service goes live. The next payment will be 1 month later. I presume that your service with your existing provider will cease when your service with Plusnet activates so there’ll be no overlap.

@Thrall  Not quite right, the first payment is taken on sign up, but the second is a month after the service goes live.

As ISP's charge in advance, there will always be a double payment, but then a month payment free after transfer.
