Hi
I want to buy bitcoin from CoinBase. I followed the steps here

https://www.c[Suspicious link removed]m/2017/06/24/how-to-buy-bitcoin-ethereum.html

(How to buy Bitcoin in seconds from your smartphone - by CNBC)

and created an account and verified my account etc. Then for more than a week, I try to buy bit coin and everything goes well but then BaseCoin send me an email to say the order has been cancelled. I tried to contact them but no luck.

My questions:
1) as per the above link, I do not need to do anything else rather than creating an account. Is that the case?
2) I heard here or searching the internet I heard something like "coin wallet" or hardware wallet. Do I need to create one so I can buy bitcoins?
3) I live in Canada. Do you know other good and trusted side to buy bitcoin rather than basecoin since I failed to buy so far

your help would be very much appreciated.

PS: sorry I meant coinbase
