My eBay account got jacked up by one eBay seller a while back.
About a year ago, one eBay seller was auctioning a whole bunch of MVS carts-individually on eBay.
The seller wrote in each MVS cart. listing, in two locations, that he would combine ship--if anyone won more than one of his eBay items. So, I won multiple MVS carts from the eBay seller.
Right after the auction ended, I asked for a new eBay invoice that reflects the combine shipping total--so I could pay for the eBay items that I had won right away; however, the :eBay seller re-invoiced me, for each cart, at the individual shipping rate. And, when i politely asked the seller to correct this over sight, he filed multiple no-bidding payer claims against my eBay account--and won each one automatically.
What's a real pain about having multiple non-bidding payer strikes is that. now I have to ask each :Bay seller, with high auction standards, for permission to bid on their eBay auction items, because eBay automatically cancels my auction bid(s)--unless the seller allows me to bid. The ridiculous part is that the

Bay Customer Service reps still want me to call the seller and make things right with the seller so he can drop the strikes from my account. (I hate call center teleprompters.) Yeah, right.
The good thing is that, not too long ago, I found out from another eBay seller that I can appeal these strikes with another eBay department and have these removed and, also, eBay is supposed to automatically remove these strikes after 18 (?) months.

I still need to contact eBay and see if I can get these strikes removed. They're a hassle.
