Vodacom no help left to hang.

Changes made to prepaid contract. Never informed of this. Can no longer transfer airtime or data to my wife or elderly Dad. When I went to my Vodacom app it tells me to contact call center when I call call center no answer automated voice told to go to my Vodacom app what now . Went to 3 Vodacom shops told me they cannot help only 082 135 can help after 10 day trying this number still cannot speak to a person. Poor poor poor service .
