Repair not done

Finally I received my phone today after it has gone for repair for seven weeks but unfortunately nothing has been done on it, it came back as I send it the reason I really cannot tell, but only American Swiss and MTN know why.<br> <br> I think they want to delay re repair of this phone till the warranty of it expires at its going to by November this year but the phone has been given me problems for the past eighteen months or so, everyone has promised to attend to it but nothing came out of their that<br> <br> Please assist me on my last request<br> Regards
