Bad customer service

Shocking what kind of customer service one receives from your contact centre. I called this morning to check if an item was available and at which store. I kept being transferred from pillar to post. Ended up driving to umlazi mnyandu mall where I was told it's available only to arrive there and they don't have the item. I then drove back home and called your contact centre again spoke to a very rude agent called Sindiswa who point blank refused me to speak to a manager after she was unable to assist me. She then put me on hold for over 7 mins which is total call avoidance. I still have not received any assistance up until now
