Quote doubled while taking out moving house cover

I called the call center to add on damage and theft as I am moving house. I got through to a trainee that gave me a quote of R966,70 for damage and R20,73 for theft. There was a communication breakdown between myself and the trainee and I requested to speak to a manager. The manager proceeded to update my details and got a new shocking quote in the region of R1800. I tried to explain to her that 2 months ago I also contacted Outsurance to get a quote to insure my goods while moving and got a quote in the same region of about R850. The manager was saying that the previous two quotes I got were incorrect as It has to be done according to the new address.I was then put through to the retention department who then had to load my old profile to get me a new quote and this went from R1340 and then to R1290. I spent a very long time on the phone and did not expect this kind of service from Outsurance staff and their lack of knowledge. Moving house is stressful enough ad my insurance company has added extra pressure on me.The system had an issue as well and was taking long to load and I told the consultant I cannot hold any longer and requested that she phone me back . Im moving tomorrow.
