Vidocom milking customers for every penny

For over 20 years I,m with Vodacom, I have a new fone on contract,no caller Id available,call customer care, response back is...I must pay a additional almost R10 p/m if I want to see who is calling me,this is absolutely nonsense cause not even on pay as you go do you have to pay extra for caller ID...one's this contract comes to an end I will move to another service provider,not impressed at all
