WORST SERVICE EVER

I am so sick and tired of Cell C and their incompetence. I have just recently taken out a second contract despite having a bad experience with my first in the hopes that this time things would be different. I got my new device on the 22/07/2022 and called on that same day to activate my device insurance and specifically told the agent not to activate insurance on my old device. She assured me that it would not be the case. This month I get my statement and my new debit order is now over R1000! Why? Because she has activated the insurance on both devices when it was only suppose to be for the new one! I called the insurance department and they could not give me answers as to why this happened and did not even bother to apologize and I was bluntly told that I will not get a refund of my money even though I never requested for this insurance on the old device. I refuse to pay extra for something I did not request for and I want my debit order amended immediately before it goes off this month. I tried to remain a loyal client to Cell C by taking out a new contract but I will never trust them again!
