Terrible service

went to Vodacom store for upgrade Samsung s7 edge and s2 watch they said that they didn't have the phone then they phoned the 4u store and they said that they didn't have the phone either for them, she said that they were getting stock on Wednesday and she would phone me. Today she sms me saying that they wouldn't be getting stock. I then phoned the 4u store and they said that they had the phone but no watch, I told them that the other store had the watch so he said he would get it from the other store for me and let me know to come past and finish the paperwork. I then get an sms from him saying that the vodashop doesn't have the watch. I went to the vodashop and they had a few watches, then I went to the 4u store and they had a few Samsung s7 edge from Monday. I spoke to both managers who tried to shift the blame to the other store. I find the service pathetic I could have had my contract renewed yesterday instead I'm going to cancel my contract and open a new one with another service provider
