Likewise, but only since yesterday nothing is posting (again).

I also recently got a survey with a home trial of a medical product. I genuinely qualified, and an additional £100 was offered for completing the trial. They accused me of never returning the product so I sent them a screenshot of the delivery tracking. The £100 then became converted to $ and points posted to my account based on the e-rewards $-> exchange rate - ~13k points. I can redeem this for about 5000 Avios/4000 Virgin miles/£30 Amazon vouchers, etc. While the £100 offer was vague (it never mentioned cash or conversion to points) so I was sceptical of what I'd get, but the points received are nowhere near £100 cash.
