Can you post the transaction ID as proof, not saying that you didn't do it, it just that everyone can claim that they've bought bitcoins, if you know what I mean. You have to be careful about how you buy bitcoin, remember that even with all this hype and the trend of the price going up, the volatility of bitcoin and the possibility of it suddenly going down is a real thing and you might not be ready for the value of your bitcoins go down which could lead you to panic sell which in the case of you buying 2 bitcoins, it's going to be a big loss, make sure that you're ready of the possibility that the price will go down because if you're not, you will lose a lot.
