So now that all is settled, along comes an email

"As we outlined in the contract we agreed when you chose your mobile plan, we increase our prices each year in line with the retail price index (RPI), which affects what you pay for calls, texts and data. This term is changing from this year onwards, where your price will increase each April according to the index plus an additional 3.9%."

So just 3 months at the "special price".
