I bought a phone cash (samsung J4 core) at Mams mall in.Mamelodi on 21 July 2020,The phone only worked for a month.I took it back to Pepcell but they said they cannot help me as I do not have.the receipt.I have the box,the phone,the charger and the earphones.I used my capitec card to buy the phone and can always produce my bank statement as proof of purchase.The total price of the phone is R2199.Is this phone not under guarantee?Most probably it is as 3 months is not yet over.May you kindly help me.
