NO CALLER ID

Since purchasing my contract from a Vodacom store i have not ONCE been able to see any incoming calls' CALLER ID's. I have been in and out of various/numerous Vodafone stores and not been assisted adequately enough for the issue to have been resolved, as promised by staff. Having no Caller ID is becoming an increasing issue as I have been missing VERY important calls, thus not being able to identify and return calls due to *********** STAFF. I feel like I have been mislead as at one point I was advised I would need to pay an additional fee of +-R10.00, not once off, but MONTHLY if I want to ACTIVATE my caller ID. NOT ONCE was this communicated to me at point of sale of my device/contract. I will NEVER EVER recommend family or friends to do business with Vodacom as I have been dealing with ONE SIMPLE ISSUE SINCE APRIL 2017. Bunch of money-hungry sharks!
