I’m not happy with the service I’ve been getting. I have been querying my premium that was agreed upon, when the first sales person who is Zamokuhle Mabena contacted me and gave me a quote, we agreed on R1455 including tracker, I also sent him numerous emails regarding the matter and he said he will rectify until today, now its R1,688. I decided to call the customer care to assist to query this and they told me they were going to listen to the call records and get back to me and I’m still waiting till today..I also sent an email regarding this matter to customercare but no response again til today.I’m on urge of cancelling the policy if this is how customers concerns are handled and also for the false adverti*****t Zamo did.
