Vodacom bad service from Benmore Pick and Pay

Unhappiness with Vodacom and Pick and Pay I purchased a new Vodacom Kicka 3 phone on 16 November 2017 from Benmore Pick and Pay to use as back up phone for emergencies. 2 months ago, the charging port has become defective and not making contact. I took the phone is as the receipt states 24 month repair warranty. The lady at the Pick and pay counter told me she cannot take the phone back and I should take it to Vodacom.I am very unhappy with the service of Cellphone counter staff. No assistance with where to go and who to call. All other retailers have the decency to take the phone in and send it to Vodacom or MTN to assess and do warranty repairs. I am now lost and don’t know who to call or where to go to sort the defective phone. Please can someone from Pick and Pay or Vodacom please call and assist on the way forward and there is zero help from the Benmore branch pick and pay. Unhappy Vodacom customer.
