Hi,
If a credit wasn't issued by the advertiser, then they were unable to confirm receipt of a correctly completed survey, and that would be an issue between you and them.
Had you received any more credits, that wouldn't change the fact that have received the same level of excellent service you received for all the other credits, and those payments would have been issued within a few hours by us.
It also wouldn't change the fact that as a result of that service, when advertisers have to later reverse credits for incorrectly complete surveys, you would still be owe us for any negative balance as a result of failing to complete the surveys correctly.
Finally, this still doesn't change the main fact which is you've deliberately missed out the full details of the service you actually received from us, which we can only assume is an attempt to mislead the readers, denying them the opportunity to receive the same level of service you received, and the opportunity to earn money online from a legitimate paid survey site.
