Disgusting Service from TFG, Quick to Phone for Money, Lazy to allocate payments

TFG has been unable to allocate a payment made at the end of February, while they continue to mail and phone me regarding the payment, I have sent an email to customer services and electronic payments at TFG, with no traction gained, when phoning in I get put through to electronic payments department with no success. CS-*** CS-***

I find it quite disgusting that TFG are quick to phone on the 2nd of the month to find out where their money is but are unable to be quick to track down money which is paid, Wish they used the same energy when tracking down money in their bank account
