I can't say that will solve the problem...it might, and it might not. I'm getting a VERY STRONG impression that the problem is NOT with KAV, but with Yuneec. What this whole situation sounds like is there's a VERY high probability that Yuneec has fallen behind...as in, seriously behind...on payments to KAV for warranty repairs. I've seen this happen with other businesses, and, unfortunately, the customers end up receiving the "bad CS", as well as claiming the wrong company.I just got off the phone with a very nice man from Yuneec who listened to all the issues with the drone, revised the repair authorization and is sending me a shipping label. It will be going to another service company, not KAV. I haven't received the shipping label yet, so I don't know where, but I explained that I hadn't heard good things about KAV and he told me it was going to another service option.
In situations like this, it is wire common for the secondary company (in this case, KAV) to start requiring payments (from the requesting company...in this case, Yuneec) either up-front, or before returning the product to the customer. When you're dealing with a large company, they can afford to bill the requesting company, as well as wait months to receive payments. On the other hand, small companies (of which I'm guessing KAV would fall under) require that constant inflow of cash to remain in operation. If they aren't receiving money from the company paying for the repairs, they become in danger of going out of business.
If my assumption is correct...and, based on everything I've read & heard, this seems to be the #1 possibility...then KAV is very-much within their right to be doing what they're doing. I'm happy that my repair too place just before this started, and I believe that the customer being affected don't deserve this...but, the one you should be blanking IS Yuneec, not KAV. For whatever company they're having you send your drone to, hopefully, Yuneec hasn't been "screwing then over" in submitting payments for warranty repairs.
Considering how much Yuneec USA has cut-back over the past 18 months, I'm seriously wondering about their financial situation, and how much longer their stay "afloat". They're increasingly facing stiffer & stiffer competition, which doesn't bode well for them. I have up on DJI, and switched to Yuneec, for a number of reasons. However, with problems like this, that's why people are considering switching (or already have) to someone other than Yuneec. Yuneec makes really good products...but, if they don't have the CS, that's a serious problem...a product is only half the equation - support is the other half.
