A Phone that doesn't touch - Consumer Complaint for PEP STORES

I Bought a phone (SAMSUNG A21s) at PEP Cell at Blouberg Mall in Bochum on the 16th February 2021. Yesterday i discovered that the phone doesn't touch. I went to the branch the refused to give me a new phone they said they have to book it for repairs and that it will take 5 weeks, the problem is that i can't afford to wait that long without a smartphone because i bought the phone for business purpose. Can i please get the new phone or you can give me just a smartphone that i can use for now while i wait for my phone to be repaired. Please get back to me.
