ABSA CREDIT CARD DEVISION CALL CENTRE IS HOPELESS

I have previously booked a flight through Skywise with my ABSA credit card. When Skywise got grounded I had to claim my ticket back through ABSA credit card devision. I have made numerous calls to the claims devision, every time waiting for about 20minutes before I get helped. Sometimes the phone gets answered by a person and then immediately the line goes dead. This is extremely frustrating after one has been waiting for 20 minutes on the line in your normal business day. Then I spoke to a person and I told her that it has been 2 months since my claim, and she must tell me what is happening. She told me that there is still a form outstanding, this after I phoned numerous times and they telling me the claim is getting processed. She told me, however that she can't see what form is outstanding but will email me as soon as she finds out. She has never come back to me. I have tried now for 2 months to get this money back, but just the thought of having to phone the credit card devision again and waiting for 20 minutes, knowing that there will be no result, actually makes me feel sick. ABSA CREDIT CARD DEVISION YOUR SERVICE IS ABSOLUTELY TERRIBLE!!!
