A claim expresses a client's dissatisfaction with a professional. On the other hand, a request for a service or benefit, a request for information, clarification or a request for advice is not a claim. We undertake to acknowledge receipt of any complaint within ten working days and to respond to it or to keep the client informed of the progress of the complaint within two months from the date of receipt.
