BAD ****EN SERVICE!

After returning my vehicle rented for over 30 days to you airport branch, I asked the assistant to please confirm my bank details as to where my fuel refund would be paid to...she confirmed the incorrect details, I however requested to change the details (this incident happened 7th Oct 2015!) she then advised me to please step aside the manager would assist me in that regard, she then helped the next client... I waited like a ****en clown until I myself had to approach the ****en manager!!! He then took my details advised it was changed , I will receive my refund with 7 days,I called back Friday to confirm my bank Ddetails was never changed! !once again I changed it telephonically yet with another stupid idiot!!!
