Bad service from Telkom

I have been trying to blacklist a ****** phone from the 9th November with no luck. Each time I call I am told I will get the ITC number in 24hours and to date nothing has come through. I need to lodge a claim and cannot do it without this number as it is needed for a case number at the police station. Yesterday Vuyani told me the number is not on their network, this is nonsense because I am on a contract with Telkom and am billed monthly. Are there fools only employed at Telkom or people just don’t care about their customers? Someone better call me and assist me
