Game information:

Electrabel
2008-01-31 : Electrabel adds €125 (+taxes) of 'breaking contract' for a contract I didn't have. They inform me of this by (paper)mail.
2008-02-11 : They only transfer €158,9 instead of everything they owe me.
2008-04-03 : After many phone calls they finally admit that they still owe me €125 by sending a 'facture de cloture' without any more info.
2008-06-05 : I still don't have the money on my account. (But the phonecenter I called last week said they opened a complaint to tell the financial department to pay me back. It usually takes two weeks they say.)
2008-06-07 : Finally the money is on my bankaccount

Nuon
2008-06-04 : €802,86 has arrived on my bank account
2008-06-05 : Letter in the mailbox to say they owe me €802,86
