It didn't help. You buy credits for responses (or fill in surveys yourself), but they are not being filled unless you boost points. Meaning that you pay double price - for responses and for boost points.
I'm sorry if the site didn't automatically allocate your survey with enough respondents. You are right about the boost points, this feature we recently removed. In a few cases, it was leading to an unfair situation.
We apologies for this.
Could you get in touch with our support staff to correct this? I hope it's still on time.
