Hello.
At the end of July I left UK for good, so I paid off my phone, cancelled my contract and took only one months tariff at the beginning of July to last me until I leave.
Since 30th of July I am not using any of O2 services and today I surprisingly received same email that I need to pay £25 for the previous month (07/26-08/26). How come If I have not used it at all and had one months tariff until the beginning of August???
Did they forget to change it or what?
