Consequences of withdrawal:
In the event of an effective revocation, the mutually received services are to be returned and any benefits derived are to be surrendered.
After the surrender of the benefits we will issue a refund within 14 days.

If the consumer is unable to return the received benefits in whole or in part or only in a deteriorated condition, the consumer must pay compensation for lost value. This does not apply to the surrender of goods if the deterioration of the goods is exclusively due to their inspection - as it would have been possible in a retail store. In addition, the obligation to pay compensation can be avoided if the consumer does not use the goods as an owner and refrains from doing anything that could impair their value.
Goods which can be sent by parcel post are to be returned at the risk of Vision Consulting Germany. The costs of return shipment are to be borne by the consumer if the delivered goods correspond to those ordered.
