Vodacom Shake it is a fakr

Vodacom don't keep their promise they lie to people on the 23rd of November I won the instant R5000 money on Shake it after several complaints they contacted me on the 6th of December and send me an indemnity form to sign and return it to them which I did the same day with my I'd copy and prove of bank account, the indemnity stated that I would receive payment within 30 - 60 working day its now March and still have not received the money from them and the person Cornelia Lawrence that was assisting me does not respond to my emails anymore
