Markhams customer service sucks!!

We went to la lucia branch on Thursday. Asked for help for the special offers on cellphones. Was told too busy to help and then ignored. We left. Yesterday we went to gateway branch hoping for better assistance but was met with a rude Mbali and Howard. At the entrance was advertised cellphone specials so I asked for help and was advised to buy the j5 Samsung. After completing the transaction and paying it was discovered that no cellphone was in the box. Thereafter the rudeness began and I wanted to buy the phone for my husband birthday today. Without offering me assistance I was told to take my money back. I left very upset. Is it Matkhams aim to chase customers away? Spend some money and teach them manners and services. I won't go back there ever.
