"Following my complaint, I was contacted by the Vaillant headquarters. They informed me that I could upgrade to a higher model by paying the difference. I accepted. The removal of the old boiler was done free of charge. They installed the new boiler. They obtained the device change document from İgdaş. Thank you very much for their attention."
