Wrong tariff

[#1]

A couple of weeks I spoke to Plusnet and was told that they could offer me a new deal. The deal was movinbg from 60GB to unlimited for £9.99 (less than I pay now). Naturally I was interested. I was THEN told that IF I locked-in for 24 months the price would be £6.99. I agreed to this.
Today on my billing date I have received an email confirming the 'new product' but charging me £9.99 !
Can this be corrected please?

Is there anyone from Plusnet who can help with this please?

Could you possibly give us a ticket number on your account so we can locate you?

Hi there,
The discounts have been added to your account, it's running at the moment which is why your discount isn't showing yet. As soon as the invoice has been generated it'll show on your account and will include the discount, so you'll only be paying the arranged £6.99 for your broadband subscription.
Hope that helps.
