There are others, but as their largest affiliate by quite a way I'm more likely to make noise than someone owed $100 who's forgotten about it. They also pulled the terms changing twice on me and less likely anyone else as I joined from day 0.
Hedgy (hi fella hope you are good !!) is slightly different as he chose the hardware credit initially and wanted to change to cash, I can sort of understand SP's position on that, but it gets murky when they have no stock left to use it on then they really should have settled up in BTC.
I had the same issue with my voucher when the SP30 was under spec, I was sure I was going to buy another from them but my available power, lack of stock or price all conspired against me at various points. In the end I had to sell my voucher for 50% of face value which was a big hit, but that's my own fault should have taken the cash when it was first offered
Imagine that......whoda thunk
