Old Mutual Iwyze Insurance Customer Care and Policy Cancellation a nightmare!

Dear Old Mutual Iwyze,

In less than 3 months I am having so many bad experiences with Iwyze's Customer Care Department. The first issue was my car inspection report, I took my car for the inspection at Glasfit and the report was sent to Iwyze; I kept getting sms's that I need to take my car for inspection even though I emailed the report to Customer Care after. Eventually I took the car back again for inspection a 2nd time. I had changed cell numbers and sent through the change to Customer Care - No response or confirmation at all. I then got an email with a letter of a change to my policy schedule which then stated that my car hire option was now removed. I queried this as well via email #REF[ ********** 1] - No Response as well. I then tried to call your Cancellations Department and could not get through and ran out of airtime so I sent the signed Cancellation Letter and my ID copy via email to Customer Care on 20th June 2018 - No response. Your Customer Care Department calls me then hangs up when I answer. If this is how your Customer Care Department deals with queries I can imagine how your claims department would be if I did claim. I have given Old Mutual Iwyze Customer Care my letter of cancellation of my policy ********** 110 via email on 20th June and will reverse any debit order on my account until my policy is confirmed as cancelled. Please follow up with your Cancellations Department in cancellation of my policy ********** 110 as my next step would be to refer this case to the Insurance Ombudsman.
