Extremely *********** and very expensive bank

I closed my absa debit account on the 9th of March 2019 and got a refund from a company into this account on the 1st of April 2019. I phoned the company that made the refund and they said the refund made was successful and I should speak to Absa. Since then I have emailed customer care absa, they said go back to this company. The company then contacted ABSA and gave me a reference number to give to Absa. I then emailed absa complaints. They said I must go into an ABSA branch. Now they have sent an email to debit card disputes at ABSA. So it has been 18 days since the refund was made, 5 emails and 2 phone calls to Absa, and a branch visit to an absa branch and still I am no further towards getting my money back since the refund was made. So it is for very good reason that I no longer bank with this bank. They are unbelievably *********** and very expensive.
