I’ve posted twice (here and here) about my problems after upgrading Vodafone’s ADSL to high-speed (nominal 20mbit, actual 15mbit) several months ago, on 17th september 2012.

On June 26th 2013, after 9 months of invoices including the extra cost of the service, Vodafone confirmed that the process was completed.
I hope that now I’ll be able to go back to the original speed and, with this downgrade, the original reliability.
