Cell C , most horrible customer experience.

So i placed a claim with cell c insurance dated 28 October 2019, sent in my documents as well as a affidavit, contacted a guy by the name of Thokonoalo, who told me my claim was denied as the SAPS stamp was not on the document, which it is on.. I then requested to speak to a manager, he placed me on hold for 30 mins, coming back to me on the phone to tell me that, he is denying my request to speak to a manager, also that its unnecessary to speak to the manager.. He then dropped the call while i was speaking to him. I then called back, came out to the same agent, he then said "Its you again" i then again requested to the manager, he then dropped my call again on me .. After an hour, i called in AGAIN, spoke to the same guy, i requested for a manager and he wouldn't get me a manager. Telling me i can just log the claim on helopter. Speaking over me, being rude and disrespectful. After i been a customer for more than 5 years... This was the worst customer experience ever
