Impossible to cancel VODACOM contracts that have reached their full term.

Vodacom is at it again! Several call for cancellation. Sudden dropped calls when they realise you are not willing to renew frustrating you for another 30 minutes and doing the same. This is daylight *******. Contracts have reached full term of 24 months but its impossible to get them to cancel. All they want to do is retentions or ***** your money for months on end!
