worst customer expirience ever( missing payments dept)

I have always been happy with the service I receive at Woolworths stores country wide, Up until I made a mistake when transferring money via EFT to pay for my store card, I provided an incorrect reference (account number)to be credited, after realizing this I called the customer service line to try and rectify this mistake. I am so angry, disgusted, disappointed, frustrated, appalled, and perplexed with the lack of service from the customer care and financial services. I have provided all the information they asked for to enable them to rectify my account, when you call to find out if my query has been resolved, I am taken from one department to the next (missing payments, queries, customer care) what made me sick to my stomach were the calls I used to get trice a day from the call center about my account being in arrears and having to explain the same story five times a day to different consultants. The work ethic of their customer care Centre leaves so much to be desired, Logged a call on the 5th of February, the query is still not resolved, the finance department managed to allocated the amount I paid to my store card account but instead of crediting my account they debited it, making my current credit to go up. It has been a roller coaster ride, dealing with a useless consultant by the name of Abib who promises to escalate the query, but never knows the turnaround time, I am sick to my stomach with their lack of customer service.
