Bad client service

I have never been so mad in my entire life! I have a contract phone with Cell C (recently upgraded) and took out an insurance with Csurance, however I've been struggle to get any form of assistance with my handset device. I took my handset device to the Cell C store at South Gate Mall on the 25th of June and was informed they will keep me updated, a month later I then decided to make a follow up only to find out that my cellphone, was never booked in for repairs and both the store and Csurance are blaming each other for their incompetency. Two weeks later after I visited the Cell C store at South gate Mall, I was then informed that they have booked my handset for repairs, however today to my surprise I am informed that no bookings were done and my insurance for the handset was cancelled, since I upgraded. The cancellation was done without my consent, I do not have any supporting documents proving that I signed and agreed to cancel my insurance for the J5 prime and active a new insurance cotract for the new handset (Huawei P20lite), then this agent from Csurance says, how should we know if you app**** for insurance online. Csurance has the worst call center agents ever. Now I need to go back to the store to collect my damaged handset, worse of it I had already paid for the access fee. How can an insurance company cancel an active insurance without informing the rightful party and how can you cancel the insurance before the contract end date. This company are making millions out of us, they seal deals without our consent and when we decide to claim that is when we are given the news. I have wasted my time, my petrol and my airtime to get proper assistance. They were not remorseful nor apologetic, the did not sympathise nor understand my frustration, they were quick to tell me to collect my device at the store, they never tried to find better solutions to solve my problem. all the Csurance agents should go back to train to better understand the importance of customer service, going the extra mile to ensure clients satisfaction. None was displayed from all the agents, what frustrated me the most they would place me on hold and hang up and at the Cell C store they hardly pick up their phone. I am unhappy and planning on cancelling my contract, because this was really a waste. I feel I was mocked by the agents and exploited by both companies for not disclosing anything from its customers/clients. The level of service I received today was just disgusting and despicable from both parties.
