Worst service EVER

Walked into Mtn Wonderpark now, wanted to upgrade our contract. First we are met by the 2 most unfriendly individuals but we keep our friendly and smile. Asked we would like to upgrade my husband phone contract, to what we are asked??? I reply with LG G6 please, so he calls another gentleman from the back office, so this guy walks out and says what are you looking for... I reply again LG G6 please, his reply... **** let me check I think I sold my last one. He comes back with and order for me, so I ask will your Kolonnade branch have perhaps, we don't know he replies. So I ask could you perhaps call them and ask, we will take the drive... They both reply with... No they won't tell us. So I say, give me their number I will call them as a client. So I call the number, but get no answer. So we look for the next option, choose a different upgrade. So I say, OK can we have this MacBook Pro with 3G and again, no stock. I ask okay, so what do you have available so we can eliminate what you don't have, turns out all they have is the Samsung Note 8... Really??? So we just went home. Really BAD BAD service. Would not recommend them to anyone!
