A bunch of typos,

The first sentence is incoherent. How much is one to two times the compensation?

In terms of the contract itself, it probably means

You signed a contract. Don't want it. If the deposit is not refunded, you will have to pay an extra fine of 30%.

If you are not satisfied with the service of the wedding company, the wedding company will not admit any responsibility and will not refund.

If there is an accident at the scene or the wedding company cannot provide services due to equipment failure or illness, the wedding company will only refund it without compensation.
