Commonwealth Games organisers are still working on a solution to their ticketing system - and the situation has got a little worse.
Glasgow 2014 has confirmed some callers to the ticket line who received an engaged tone were charged in error by Talk Talk - who supply Ticketmaster.
They've apologised - and are working to compensate customers.
Sales for an extra 100-thousand tickets, released on Monday, remain closed after problems with transactions and long delays.
A Glasgow 2014 spokesperson said:
"Glasgow 2014 can confirm that some callers to the Glasgow 2014 ticket line who received an engaged tone on the ticketing phonelines were charged in error by Talk Talk Business, a supplier of Ticketmaster.
"We apologise unreservedly for this and are working now with Ticketmaster and Talk Talk Business to ensure customers affected by this are refunded these charges as soon as possible.
A TalkTalk Business spokesperson said:
"It has come to our attention that, due to a human programming error, we did not deliver the service that had been agreed with Ticketmaster during the general ticket sale for the Commonwealth Games. This meant that some customers who called the Commonwealth Games ticket line and received the engaged tone were charged for the call costs in error.
"We would stress that this issue did not affect all callers to the ticket line and we sincerely apologise for the inconvenience this has caused. We will work with Ticketmaster to urgently compensate all customers affected by this error."
