im still on hold after 3 weeks

i have been trying to call mtn insurance for the past 3 weeks now and im always put on hold and then after half an hour it cuts off. I have emailed my queries as well to the address prompted by the voice instruction. it would seem like mtn insurance has closed shop. then you hear mtn scandals in Nigeria, mtn ***** collusion with fnb and you wonder if my query is not part of the *****. I will email again tomorrow and im sure nothing will happen. I just want to cancel this insurance and move over to the other reliable networks
