Poor service, Hellish nightmare experience, worst deal ever , would not recommend

Vodacom has offered migration from 3G internet to fibre to my mom she took up the deal and to her surprise she was debited the fibre amount and 3G amount the debit order now became to expensive to bear, as my mom is 68 she asked me to intervene, to date Vodacom advised they will listen to the calls and adjust the debit order and refund the basicaly ****** money that was debited for the #G service that was no longer in use, to date nothing has been resolved and the expensive debit order continue, I am no forced to take further action and got to ICASA to lodge a formal complaint, we want everything cancelled even the fibre and we want a credit passed as vodacom sold us a **** deal
