That's how ordering online works

I reviewed this company before, it was clearly as I did not know , what was waiting for me, I really took my time to decide on a phone, now understand about Display, RAM and storage , I looked at everything, looked at unboxing reviews, and decided on a phone, the A32 , with 128G , and clearly, as stated on the website, 6G of ram , first problem, I ordered black , man phone me , He only have a blue one , must he send it , I said yes, received the phone, and as it was a hectic week at work , I only opened and set up the phone, the next weekend, after everything was done , I noticed that the phone, was lacking on its speed , had a look, and with a shock noticed , The phone only had 4G of ram , and I already used 3.1G , so the phone was going to become, slower etc, I actually phoned Rentoza, before ordering the phone, to ensure, that it had 6G of Ram , the poor man o spoke to , confirmed it , but he was most probably, looking at the same screen, I was looking at , now I took a screen shot , from the description, from their website, and sent an e mail, to now ask , why are the advertising one thing, and then sending another , so my conversation , with a Richard started , he apologized, noted that it was their marketing team , who made a mistake (in writing) and asked if I could look at something else , eventually, I agreed , this is when he told me , I must go and order the new phone , on the website, and pay , so he can carry on , when I asked about the money I already paid, as it was not my fault ,they made a mistake, he answered me " that is just how online order's work !!!! , when I then said, that it is not acceptable, I received a mail, that I must send the screen shot , were it shows the 6G Ram , I again send it , now all of a sudden, I received an e mail from a Nomfundo Ndlovu , who took so much intrest in my matter, that she said, I must send the screen shot were it shows that it is only 64G memory??? For days , we have been discussing the Ram of the phone , and here this person, is now going on about something, that was never even mentioned, when I rep**** , the problem us the Ram and not the 128G that's a problem , I received no reply, yesterday on the same mail, I asked for feedback, no answer, and absolutely no feedback from Rentoza, so now , they advertise phones with incorrect information on the website, and then expect you must give up , the full first payment, you made , to replace the phone, because " that's how ordering online works "
