Online purchase- No reference or tracking number received

I visited game online store on Monday 4th June to purchase a camera at the value of R1899.00 using my game account, firstly my one time password was sent to a number that I never provided to them and I called Rcs with this matter and they were able to sort it out. I then managed to receive otp to complete my purchase but the funny thing is I didn't get any reference or an email confirming my order, the only thing I have to prove my online purchase was an SMS stating the amount debited from my account. Well I then decided to visit the store after I called online support and they advised me to visit the store and ask for my account statement since I didn't receive any reference well when I get to the store I was told that they cannot be able to assist me with this matter as they can only print out the balance not transactions made. Now I don't know what to do because it seems like no one knows how to resolve this matter, I used to trust game so much but after this I lost trust. You guys are very ***********, looking at the reviews here I'm not the first person to experience this but yet you still don't know how to resolve it.
