Hi Mr.Sylvi Wijesinghe,
sorry for the delayed response. i've been abroad for the past one week. and i called the contact u gave by right now; i guess the number u mentioned might be wrong as he said he dont handle DPF issues. and the name you mentioned is not the one who spoke with me. he said there is no one known as Mr.Dilantha karagala. if u can please double check revert me. awaiting for ur reply.
thanks in advance,
