New Account is Messed up

I waited for an hour to collect my bank card at the bank.<br> I opened my account online and went to collect my card at the branch on Saturday at Northgate and the bank closed while the consultant was busy helping us.i signed all the relevant documents and did not get to deposit money into my account because the bank was closed.<br> i could not go to the bank on Sunday and now it turns out my account is closed.<br> No one called me to inform me that they are closing my account.<br> I just moved from another bank and I closed my account at that bank.<br> How on earth is this happening and why is it happening?
