Finrite insurance - *********** bunch!

Finrite insurance is the most unhelpful and extremely useless. I have a contract with Vodacom and cancelled my insurance with Finrite on 25.04.2019 effective immediately. I was assisted by Thulisile Makobane at 08.51 and she advised that this has been cancelled effective end of April and I would not be billed for May 2019. I called again on 13.05.2019 and spoke to Nooreen Smith at 10:20, she advised me that this has definitely been cancelled and that I have been billed for May 2019 incorrectly. She sent an email to policy admin to correct this. Followed up AGAIN on 13.05.2019, spoke to Mercy Sadiki at 11:51, she also advised that the bill for May 2019 is still reflecting, sent another email to policy admin and told me it would take 24 hours to update. I have had enough of this bull**** as I AGAIN called in today 27.05.2019, spoke to Khahliso Metsing at 08:30 and requested to speak to her manager Phandelani Sethaladi who refused to take the call and rather let her promise me a call back. Talk about shunting ownership. FINRITE INSURANCE are absolutely useless! Their customer service stinks!! I expect a call back and resolution immediately!!!!! As I result I am holding back payment to Vodacom until my bill is corrected! There will be hell to pay if I am handed over for **** I cancelled in April!
