Barclays customers have reported being unable to access their money or make payments over the weekend.

The bank said it has been "experiencing technical issues affecting some services" which were being "investigated urgently" yesterday.

Barclays said today it was still fielding "high volumes" of calls form customers.

Customers are still reporting difficulties accessing cash and making payments, with some also claiming their debit cards have been blocked.

Barclays said the problem had been fixed and asked customers to use online and digital banking services instead of calling, due to large numbers of phone enquiries.

However, some customers reported they were still having difficulties accessing their accounts.

A Barclays spokesperson said the problem was internal and was not caused by someone hacking into its computers.

Concerns about cybersecurity are high after hackers accessed personal information, credit card and bank details of TalkTalk customers last week.
