O2 does not allow calls to Betamax since long time now.
Recently on 12-10-2009, E-plus - BASE blocked calls to Betamax completely. I was able to call in morning of 12th oct and from the afternoon all calls are blocked. Now I am stuck with BASE as I have 2 years contract.
Is it legal that any company can block a landline number on a landline flat tariff ?? See the news.
