I am very disappointed with your response regarding my request.
I asked COA and your corrective action plan for contamination again.
But I have not received yet.
Why do you take so long time?
I can accept for delay of corrective action plan, you must be taken more time to find solution.
But CoA is totally different.
I think you cheated me last time, so I asked again.
If you did not cheat me, then you must send me asap.
I cannot wait for your reply any more.
I will consider you do not test MV and send my report to HQ & R&D including my opinion.
I am sorry to say like this.
