I made a purchase during the pre-sale, and got a receipt from OLXA. However, I have not received tokens in my ETH wallet, nor do I see any indication that I have tokens on the OLXA web site (it shows my bonus tokens, but not for the ones I purchased). Is this expected?
yes this is correct.
You will get your tokens in 24-48 hours from your purchase date.
i got mine in 15 hours without problem, so just be patient, what am i saying if you arent patient dont do ICO´s
