Charged double for a trip and Uber refuses refund

Last week I had a trip with Uber. The amount for tgis trip was debited 4 times and reversed twice. I alerted Uber to this and was advised that it was simply an authorization hold and within 3-5 days it would clear.

This time has since passed and I have contacted the bank, who confirmed that this amount was debited twice. I once again informed Uber and constantly receiving a copy and paste version of the same standard message that it is an authorisation hold. I responded and advised that the bank confirmed that it was a double debit and have not had any resolution since.
