In this case, the Customer agrees to early action by the ISP at the time of conclusion of the contract, so that withdrawal from the contract is not possible (or no longer possible to the full extent).</p> <p>If the Customer asked the ISP before concluding the contract to commence contract performance before the withdrawal period ends and the Customer withdraws nonetheless, the Customer must pay a proportionate amount of the agreed fee to the ISP. If the ISP has already performed the contract in full, the withdrawal right ceases to apply and the full fee is payable.</p> 1.4 TRANSFER OF RIGHTS AND DUTIES. USE <p>Without prior consent, the Customers of the ISP are not authorised to transfer all of the rights and duties under this contract to a third party. However, individual rights such as repayment claims may be transferred.</p> <p>The ISP is authorised to transfer its duties in full or in part, including in relation to individual services, or the whole contract with debt-discharging effect, to a third party and to notify the Customer of this. This does not apply in relation to Consumers. The right to use vicarious agents shall remain unaffected.</p> <p>The use of the contractual services by third parties and the transfer of these services to third parties for a fee requires the ISP’s consent which, except in relation to Consumers, must be given explicitly and in writing.</p> 1.5 NO POWER OF ATTORNEY OF THE ISP’S EMPLOYEES <p>Sales partners or sales employees as well as technical assistants of the ISP have no power of attorney to make statements, give promises or accept payments for the ISP. In relation to Consumers, a limit to the power of attorney or a missing power of attorney of the sales partners or sales employees of the ISP only applies if they had knowledge thereof.</p>
