American Swiss customer services

I called AS customer services to find out how to return a birthday gift. From the moment I questioned the call center agent about the company returns policies he started to have a very bad attitude with me and thus began me being put on hold. This would continue for the next 17 minutes. When I tried to escalate the matter to a supervisor they where all in a meeting..then I am on hold. I point out that this is a customer services center how do you service a customer when all leadership is in a meeting? I am hold again. Out of sheer frustration I cut the call. My gift was bought by someone from Durban I am in Johannesburg, so they scanned and emailed a copy to me. My query was simple will this be sufficient to return the item. As I was told 2 weeks ago by AS staff that I need a slip to return the item. It seems corporates are eager to take your money but never happy with after sales care. Appalling service.
