Blocked account

I went instore on the 5th of May 2019 to unblock my account after someone tried to use it **********ly online. The manager called the accounts department and they told me there was a different cell number registered on my account that I didn't know but I assume they fixed it after we spoke . And they told me my account would be active after 5 minutes. But still today my account is still blocked.

Can I get assistance please.
