Ikea IT isssue charged twice

Shaken_not_Stirred

Hi All,
Was in Ikea Glasgow 3/8. My sister was purchasing wardrobes and as she was paying for the items there was an IT issue that aborted her transaction. After an hour at CS desk they confirmed that the order had been cancelled however they could not stop the financial transaction at the store and apologised as it appears the payment had been put through twice ! They had escalated and would be resolved quickly
She confirmed with bank and sure enough two pending transactions for over £1200.
One week on , daily calls to Ikea , one attempt 4 days after purchase by Ikea to cancel them with the bank ( Ikea didn’t give sufficient info for bank to cancel ) and the transactions are still pending. This effectively means she cannot access this money in her bank.
They advised her case had been escalated on Friday and new email would be sent to the bank to cancel.
Bank have advised that in a few days they will drop the pending transactions and funds can be accessed however unless Ikea send a correct email to cancel they can re-request funds for up to a year.
The matter I’m sure will be resolved soon :mad:
Any advice on next steps ?
Would she have any rights to compensation for the stress , calls and not being able to access her money in the bank ?
