AP defective service and turnaround

[chmk]

I sent my watch off for service (it was less than a year old and had already started to run extremely slow and wouldn't keep time), and it was prompty returned within 4 weeks of service. However, within a few days, the chrono stopped working and the watch's rate was inaccurate, far outside the boundaries of the tolerance. It is clear that a service again will be needed... does anyone have any experience with situations like this? Will AP again take the estimated 4 weeks of service, or given that it is their fault for an initial defective service and I have only had the watch back for a week, will they try their best to expedite the process?
