Vodacom is useless

Worst experience ever over the last month from Vodacom. on the 19 October 2022 I purchased a cellphone online, it was once-off purchase. RAM Couriers had returned the phone after multiple attempts of delivery - which was not true as they only contacted me once. The phone has now been returned to Vodacom and no one at Vodacom can assist me. I have called the Customer Care, the online store number and every other number that was provided to me and I keep getting stories of we cannot assist you we do not deal with once-off purchases. I am at my wits end. I have not been contacted by anyone to say the phone has been returned, I have not been refunded either. I need my phone or i will be opening a case of theft.
