Poor service

I am highly disappointed by Absa Bank as I was supposed to have been refunded by them with a refund that I received from medical aid.I received an email stating that it would be done within 3-5 working days last week Thursday,I then called the branch administrator at Table Bay Mall,who was the one assisting me with this transaction,on Tuesday to do follow up,she then responded by telling me that it has been approved and that it will take another 3-5 working days for the money to reflect in my account.I was not happy about that,I then spoke to the branch manager yesterday morning and she promised to do follow up.Yesterday afternoon I receive a call from the branch manager saying that the money will reflect either last night or today,there’s still nothing in my FNB account. I mean how long should I wait for MY mine!!
