Does buying more bandwidth remove connection restrictions?

[#1]

Hi there
I've watched a few World Cup games on STV/ITV's HD service and didnt realise that it was so heavy on bandwidth.
Just checked my email and apparently I've used over 17gb for the month (Email ref: E0191) and I'm not much more than a week into this months rations. Also the connection is so slow now any video I try to watch buffers every few seconds.
If I go and purchase more bandwidth (10gb perhaps) by this method ---

--- will my connection restrictions be removed?
Thanks, H.

Hi Harry1888,
you are on PlusNet Broadband Premier Option1. The link you posted for purchasing more bandwidth is for Broadband Yourway (BBYW) packages. Unfortunately there is no way to add extra usage to your package. More information about your package can be found at:

I think you'll just have to use your broadband sparingly until your upgrade to extra takes effect.

Can you manually move the changeover to extra forward

Hi Jim, If we were to do that it could cause issues with usage reset,  usage periods, contract dates, double billing. For this reason we don't change packages until the next billing date.

Ah, right, cheers guys. I accept it's my fault but 2 and a half weeks of this is going to suck 
On the upside, the Extra package looks much more suitable and it's cheaper. I went through the 'change product' process to move to Extra but I'm not sure it worked. Can you confirm this will be the case for next month Jojo?
Thanks again, H.
