Yes, I had over 2100 Positive Feedback and my account was limited to 50% of selling, I normally sold over 300 items per week, so it came as a blow!
Anyway, there reason was my feedback wasnt good enough, even though it was around 99.3% Positive! I emailed anyone who left neutral and negative feedback, and got them to withdraw feedback as a mutual agreement - I know it hurts! Then I contacted ebay and told them the others who hadnt responded were unregistered users, and my account was re-instated in less than 4 hours.
If you telephone ebay, it depends upon the person you speak to, their mood at the time, I initially spoke to a French Guy as Im based in the UK and he told me my feedback was totally unacceptable! And the matter would not be reviewed before the month was up and if I called back my Powerseller Telephone Support would be withdrawn. Hence the use of Mutual Feedback withdrawal and then I spoke to someone with an ounce of sense - WHERE DO THEY GET THEIR STAFF!
I received an email from Powerseller Support After asking about the assistance from their staff so I told them to shove the Powerseller Status Up their *** you fill in the word...I no longer need Powerseller status as its more a hindrence then a benefit.
