If you have proofs against the user you can make a thread here, many users have neg rated him for same reason I doubt any user will use his service if they look at his trust rating.

Just wait for transaction to confirm you don't need to worry also provide your transaction URL so people can help you accelerate it, I have received my funds even after 15hrs+ on Localbitcoins wallet due to to low fees you don't need to panic already.
Edit - if its about buying BTC hoping for seller to cooperate with you or contacting the support is your best shot hope it gets resolved.

I had used this site like a year ago they are legit and I have got my payment few times from them its a fun game and the faucet used to be more rewarding when I used to play because the site was in beta stage, also you should mention about your referral link behind that url.

Its pretty safe if you do deals on site but if you just contact the seller directly via his contact details or in person even if he has really good trust rating you are taking the chances here, I had done this mistake and had a bad experience if you are doing trades on site there is very less risk I have not done huge amount of trades just a bunch of them and no issues till now.

I am sure they check everything manually if the campaign is managed by a user-manager and about char count i completely agree with @shawn, there were campaigns in the past which were automated by script post count etc only the payments were done by admin if i am not wrong, but that lead to spam because the bot was not capable of checking quality of the posts, you can check the campaign thread to find out how its going to function.

Transaction is confirmed now you don't really need to panic and make a thread if your transaction is not getting confirmed, there are many users who provide free acceleration to your transaction and helps it to confirm fast without any charges use them if you find yourself in the same situation again.

How often do you provide a giveaway and average how many giveaways are done in a month? just subscribed interesting concept looking forward to giveaway updates.

I had seen a user advertising his telegram group which connects users who want to sell/buy their cloud mining hashrate for lower price, I wouldn't recommend using cloud mining though as other users mentioned its not profitable and you might even lose your Bitcoin if you invest in a site without researching.

What if you fail to provide the answer for the question which client asked you? on what basis are the fees calculated? you might be a legit doctor with positive motive but this kind of service is strange and new here really hard for users to digest or trust on you.

His Recent feedbacks are negative and neutral 14 days period to claim money back it might take longer than 14 days to reach you if you don't live near the seller and the return policy looks fishy, if you have the money to play it safe I would recommend you to buy from a more trusted source.

I would vouch for yahoo he is good at what he does and I have joined many of his campaigns he is very professional.
