Consumer Redressal

I have submitted my newly purchased sony Xperia Z1 compact mobile phone for fixing up quality related issue (charging cap misfit getting opened automatically) to DG mobile services panvel on 14th September. As per DG mobile services mobile phone was not repairable hence they have send to sony for swaping it with new set. After rigorous follow ups and emails I got call from DG mobile to collect the phone, however when I went to collect I found it an old set having scratches on front and back side. I denied to take the piece and complaint to sony service head for returning my set after repairing or a new set as my set was brand new with front screen guard and cover as well. Its over one and half month now but there is no solution to the issue. I am still following with every one at Sony but there is no resolution yet from any one at sony.
