Doubtful or Incredible Connection - Before purchasing online from Incredible Connection, rather use Takealot

Purchased a online Xbox voucher yesterday and I have still not received the voucher code even after speaking the Mcebisi in customer service yesterday and again today. Amazingly Mcebisi is telling me to be patient for a a voucher code that usually is received within minutes from purchasing online at incredible connection. Mcebisi has also now decide to ignore me . I now purchased it from Takealot and within 60seconds I received the voucher code.
