Royal Blue Wash & Wear Regular Fit Trouser

I am regular customer of diners from more than ten years. I ordered a pant in first week of March but unfortunately with wrong waste size. I paid and received cod then posted it back to diners at SITE Karachi which was received by them on 13 March 24. I was informed that they will generate e voucher on the same day but it's been one week I am waiting for voucher. All contact numbers of diners are off or they blocked me. Not even replying me now. Is this the value that you give to your regular customers?

Nice fabric and color as shown in picture.

Really nice and comfortable stuff.. I am fully satisfied with product quality & stitching. However customer service is very pathetic, after so many reminders and messages my order was despatched.
