Any payments made under service contracts with Conzia are non-refundable as Conzia GmbH will invest time, expertise, and effort in delivering the agreed-upon service under service contracts. Since these resources cannot be reclaimed, refunding the payment will not be feasible. Once a service has been provided, it cannot be "returned" in the same way a physical product might be. The services agreed upon under this contract cannot be exchanged with any other services outside the scope of this business.
