If a lawyer of your law firm provides legal advice or performs legal work which is wrong and which causes serious material damage to me, will your law firm pay compensation and how much is the amount of compensation?

If a lawyer or supporting staff of our law firm provide legal advice or performs legal work which is wrong and which causes serious material damage directly to a client, provided there is clear evidence of such we will be liable for material damage to the client in accordance with the current civil law. However, in all cases, the amount of compensation that we shall pay will not exceed the total amount of service fee that we have received from such the client for that assigned work to the date of compensation
