Vodacom *****

Spoken to a Cassandra at Vodacom that promised me my money would have been paid back in 7 working days. It's been 15 days now and no payment has been done. When I try and email her, I get no response. When I phone Vodacom, no one knows her, or they say she works in a backoffice and that they don't have a number. I don't know why the customer must call Vodacom for a mixup Vodacom made for adding numbers to my name without my approval. So hopefully someone will contact me to sort it out.
