We are serious for our client  EVASTON   loss of their work. Now, you need to pay an amount of Rs.9215/-. As per an Indian Penal Code section 420 shall be imposed on you if you abscond from the situation. Now, you don't pay that amount what our client is demanding for then, you need to pay double amount and legal notice will be issued to you. Still, you fail to pay this amount then, we will call you here for legal proceedings. What should i do now this company is in surat gujarat r all saying they are doing this only fot money this is fake company
