Pathetic service and poor communication on changes to their policies

I recently put a claim in for household contents where my appliances were damaged due to a power surge. After their assessors came and viewed the damaged goods the claim was approved for the home theater.

Now they apparently changed their policies in Jul 20 to only pay out a maximum of R5000 as they sent an email with the changes affected to the essential plans. The replacement value is R25000 on this home theater.

After speaking to a "Sandile" as their customer service team they said an email was sent out in May 20 confirming this change. I have NOT received this email! Yes I was frustrated as you can imagine and used some vulgar language but then he refused to put me through to anyone else. THIS SERVICE IS PATHETHIC TO SAY THE LEAST! I have been with Discovery for over 6 years and paid my premium on time every time! Such a major change to should at least merit a phone call?

I will be cancelling and moving away from Discovery.
