6 or 7 MONTHS? Sorry but no. There is No RMA out there that should ever take that long. There is no reason to dig up a thread from that long ago. Heck we barely keep people on this site week to week, let alone dig up a topic from 7 months ago and expect the OP to come back and respond.
The longest i see for RMA's is 4-6 weeks which falls way within the 3 Months period of 12 weeks. That would be double the length of any good RMA. At that point if it went 3 months and you still havent gotten your parts back, i would be calling for a refund.
As Trotter said, the OP can ask for it to be opened and get it going again.
