He refunded me.

How do I go about messaging someone about a seller ?
I paid for 100% tier 1 traffic - don't know if I got it . Very low opt-in rate of 7% perhaps asking why the opt-in rate was very low .

if you order top tier the udimi system will make sure you get them and about low opt-in please message the seller you order clicks from

So another top seller so assured me was legit, now waits 7 days after I paid to refund order after saying everything was good to go? I mean seriously? Is it just the sellers in this website?

No there are a lot of good seller here

you should always use your own tracking system to ensure you know what kind of traffic you're getting. You can also use it to track conversions and sales. How do you know if traffic is working for you if you don't track a keep metrics.

SO I messaged the seller whose add specifically stated 100% tier 1 . I then tried to locate the ad - low and behold it had been removed . I turned down his special offer in his reply , I showed a receipt that states I paid $33. more than he said I did . Then he offers to send 100 clicks as a test run ...free - I have yet to see those .
I am frustrated with this seller . There may be many legit sellers , Though it seems there may be more sellers sending window shoppers and then try to talk their way out of a refund. It only takes the poor actions of a few people to spoil a whole site of sellers , many who are attempting to make an honest living . My business will no longer be buying from Udimi .

I just had a bad experience too. I contracted Tom and got no sign ups and no sales. Is this site a scam?
added laterI wrote and told him at what he said was 61 clicks and he did nothing. Meanwhile other people are buying these solos. I think this site needs to improve radically.
added laterFor 100 clicks I could go to easyhits4u but everyone knows you get just visits and no clicks. Supposedly solos are the top quality deal that gets at least optins if not sales.
