Very dissappointed with your services

My grandmother opened a R120 top up Cellphone contract with Vodacom. She explained to me that the caller identities only shows as unknown number. I have confirmed all the settings on the phone and they are all correct. I then phoned Vodacom and they told me that caller identity service is a add-on service that is not included on the contract. Vodacom I am very dissappointed. I am changing my service provider immediately and will make sure that everyone else does the same. Shame on you!
