Beware of upgrade telephone calls

Beware of the telephone calls to upgrade. Vodacom harrassed me and told me I have no choice but to choose a new package. They forced me to choose a device. Then they also RE-ACTIVATED a device (mobile modem) from 7 years ago and are no charging me R1300 extra. I drove to head office and spoke to Judy Chetty. She made me sort it out with THEIR SUPPLIERS, this is an out-sourced company that does the upgrades. My contract with Vodacom. Vodacom takes no responsibility. Still not resolved for 3 months.
