I have several direct debits on my Starling account and i was told by BT that I should cancel my direct debit while they were looking into a payment query! All went well and the direct debit wad canceled!
The trouble has been when setting up a direct debit as Starling systems keep denying the requests as the REFRENCE is the exact same as a previously canceled Direct Debit!!
BT say the REFRENCE has to be my BT account number and Starling say it needs to change, so I am stuck with BT who threaten charge me extra (Line Rental Plus whatever that is) and having to remember to pay each month on time!!
Never had this issue with the main banks but find this a major bad point with Starling!!
