Unhappy with Vodacom repair services and poor customer care

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 Pick and Pay Manager named Sam was very helpful and logged my repair with Vodacom with all paperwork on 14 November to Vodacom. Vodacom has provided zero feedback or assistance with where to go and who to call. Vodacom should have decency to communicate with customer warranty repairs or even acknowledge receipt of the phone but THEY DO NOTHING. I am now lost and don’t know who to call or where to get info. how long it will take for repairs and whats wrong with the phone. Please can someone Vodacom please call and assist on the way forward and there is zero help from your call centre. Unhappy Vodacom customer.
