Lake Como blunotte cost

Hello !
We are getting married in lake Como at Villa Geno in May 2024 and we received our quote by blunotte eventi and it was 7000 euro for a 40-50 person wedding . We are astonished as the numbers we were “quoted” before we signed a contract with Villa Geno was alot less . They actually did not include many charges in the original quote . We now feel we are put into a hard place because Villa Geno does not let us use any other vendor. Has anyone had a similar experience or any suggestions on this issue ? We also had additional information seen cost with Villa Geno as well . Such a terrible experience from both companies 😞
