During purchasing and negotiating the details , Mr Nelson has time to wait for us because there is time lag between two countries . when there are defective happens, this is our duty to ask the defective details , we ask for further information to analyze all the possible reasons. Mr nelson starts to think we are finding reasons to escape our responsibility. And starts to say we do not reply him when we do not reply you immediately, we were sleeping time, we have replied him once we are in office or we are not in sleeping . We sent him the replacements free too . his mechanic cannot handle these , Mr Nelson also say our responsibility. Before we send out replacement, the informations from Mr Nelson have not been enough to prove it is the spare parts quality problems, we still offer replacement to him free.
