Bad service with the customer care

I would like to lodge a complaint with the Ackerman’s customer service.I came to the Ackermans in woodmead center in an attempt to find out about a debit order I arranged in May and why the amount was not deducted and an individual by the name of Christopher helped. He then called customer service to find out what was going on the first call was made and I talked to the consultant who then asked for my details and then put me on hold for 15 minutes which I ultimately had to hang up because I had been waiting for too long and the store was about to close. The second call was made and Mandisa the consultant answered and to my dismay the same thing happened again. I am very disappointed to say the least,that a minor issue such as this would cause a wait of 30 minutes just for assistance. Bad service...
