Untrained *********** staff payjoy

I went to payjoy for a new phone and by the salesman I was told this is a monthly payment structure so I agree on that. So I was applying for a new Samsung A36 and after a while I was told that the A36 is out of stock butt he can give me the A26 with a very hard decision the salesman sed to me its actually the same as the A36 screen size is a bid smaller butt when I got the phone and via Google the A36 and A26 screen size us the same so he managed to sell the phone at me butt here comes the catch after the deal was done he told me that I must pay in 7days time R258 or the phone will be blocked With numerous calls and emails I managed to get hold of one of the ladies in head office and I spoke to her about the storie of the payment plan then she told me ser you can make the nesserly payment with my salary pay date now when I go into the app there is a message that say I have 2hours left to make the payment of R258 or the phone will be locked so what kind of company is this sells a phone at you and its the wrong phone and wrong information given to you is going to lock the phone this is dew to untrained un *********** staff that selling phones with *** information
