Barclays Credit Card Complaint

Barclays Credit card department,

Billing disputes New York

I have paid Barclay bank - for - months. I have paid what I believe to be the monthly charge plus extra toward my past due balance. I have a statement sent to my email monthly from Barclay with a link to log on and see statement. I do not remember my log on information. I have called the company to request help and am directed to a collection agency that will not give me my full account information or any other assistance to log on and see account. They state they do not have access to that information as they are a collection agency. They will not connect me to Barclay Bank to request assistance stating Barclay does not have my account, yet they send me an email monthly with statement. I am unable to switch to paper statements as I do not know the account number. Someone from this account calls me daily for collections despite my paying weekly.
