Discovery bank poor service no help

I visited Kiara Lodge in Clarens during the Easter weekend and the lodge asked for a credit card so they could hold funds of R1500 as a security deposit and when I check out they will reverse this amount back to me,I checked out on the 24 April 2025 and recently called the lodge on the 06/05/2025 to query as the authorisation is still pending they then sent me an email where they have requested their bank FNB to release the funds back into my Discovery credit card but stated that they always have a problem with Discovery and I must call Discovery.I called Discovery on the 07/05/2025 and the consultant does not want to assist and is requesting I get a official letter from Kiara lodge and he seemed disinterested to assist.This bank is useless and pathetic I will be closing this account very soon.Please do yourself a favour and stay away from this useless Bank.Dsixocery bank will not help you when you need assistance!
