Sorry about this.
Regular airmail is very slow but at the same time your order is taking quite long as well. We can offer a few options:
1. Refund your payment in full through original payment gateway or store credit (gift certificate), at your choice.
2. Send you the free replacement via registered mail for delivery, for a $2.00 fee. This is to cover registered mail fee only.
3. We can also send you a free replacement again using free regular airmail. But because of your initial experience with regular airmail, we do not recommend this and would rather refund you in full.
FastTech offers customers the freedom to choose shipping method during checkout. If everybody selects DHL or Speedpost(EMS) during checkout, everybody would be happy. Unfortunately that's not neither the case nor is it realistic.
Short of that, we have no control how the postal systems handles your package and please understand that at this point all we can do is to follow up and do what we can.
Please let us know of your preference and we'll arrange immediately.
