Account upgrade

[ricksmith]

I’m currently signed up to full fibre 150 and pay £28 per month 

I  would like to upgrade to fibre 500 but find there is no option available to upgrade my service in my account dashboard. However if I search talktalk broadband I see that fibre 500 and 900 is available as an option for other properties on my street. Also I find that the price of fibre 150 is currently being offered for £26 per month £2 a month cheaper than I’m currently paying. 
Could someone please advise why I’m not allowed to upgrade and why I’m paying £28 and not £26 which is the current advertised price.

Offers regularly change and some deals are better than others.

You will need to speak to the loyalty (better value) team to discuss your upgrade of its available. This team also holds the best prices and offers, so its worth a call to discuss 500 or 900.
