Unnecessary charges by vodacom

Recently took 2 contracts with vodacom, when I receive calls they are all unknown, called the call centre and I am told I must pay R100 per number(R200.00) in order to know who is calling me. I have never heard of this mediocre in my life, in addition to my contractual amount I must pay R20.00 extra every month to know who is calling me. I was thinking of taking other contracts for my kids but I will not.

This is a pure **** reaping people off their hard earned money, why should I be paying to know who is calling me.

Absolute poor service by vodacom
