3.2.(2) Pro+Motion GmbH will undertake to notify the contract partner immediately of the change in the service. The contract partner will have the right to cancel the contract or to demand another service that is of at least equivalent value. The contract partner must exercise these rights immediately – but at the latest within a period of one week of receiving notice of the change. The contract partner will, however, only be entitled to the above-mentioned rights if the change is considerable and relates to a material contractual service. The right to another, at least equivalent service will also be conditional upon Pro+Motion GmbH being in a position to offer such a service from its range of services without added cost to the contract partner. If the contract partner fails to exercise these rights within the set period, the contract will apply with the advised changed conditions and in so far the contract partner will be unable to assert warranty claims.
