TRYING TO CANCEL!!!!

Iv decided to cancel my vodacom contract as the data charges are becoming too much. Iv decided id rather get uncapped wifi from TELKOM as the uncapped is around the same price. I called the vodacom cancellations department and i get put on hold by the answering machine. 5 minutes into the holding period i get cut off for no reason. I call back and get put on hold again for 7 minutes before i cut the call myself. If theres no one to answer the phones, inform clients. Dont leave us on hold the whole time. Just another reason for me to cancel
