Online shopping nightmare

For years I have been trying to register for online shopping and each time I will get an error message. I would drop the online part n go to the nearest shop unfortunately for me this time the item is only online. I called in to get the error fixed n was told they have reset my profile I can try again in a while still nothing. Then interesting I was told no u can buy without a profile using ur card I did today it’s Wednesday 3 days later I am yet to get my order confirmation. Make everything available in ur million shops coz your company and online don’t gel
