Vodacom initiation fees

I activated my Vodacom contract today and was informed that an initiation fee will be deducted within 48 hours. I explained that I requested that all fees must be deducted on the 1st of each months. The account section refused to assist me and said the initiation must be deducted regardless of my initial instruction or financial circumstances. I logged a complaint at Vodacom customer care ref: S3-85W2V-VFPEH
