Discovery Bad Service and Uns****ed Call Centre Agents

I am highly disappointed on discovery service, I had my personal medical aid with discovery since 2014. Early this year I moved to my husband medical aid. I asked discovery to transfer my savings to my husband medical aid they refused and said they will pay back my savings to my account in 4 months. I was asked to send a form requesting the claim and baking details for refunds. I sent the form the end of June 2017 and called to confirm if the details change and was told that it will be changed. After few weeks of I received an sms they changed the banking details , logged into my discovery online and it was changed. On the 1st December 2017 I called discovery to check when will I get my money , the call center agent said on the 11 December 2017. I then asked him to confirm if my banking details has really changed and he said they have changed. Today I call to ask why didn't I receive the money, I am told that the money has been paid in to the ABSA account that I cancelled in 2013 and I have to wait for it to reverse first before they can send it to my account. That's after I was told to wait for 2 days to see if it will reflect on my FNB, then I was told to hold so they can check with finance only then I am told the money is paid into the ABSA account. I am so disappointed and irritated with the call center and discovery service because I called 3 times to check if the details are correct and the time they agreed with me and now they want me to send the email of my details again. I fail to understand how will the email help if it didn't help me 4 months back when I claimed and why would my online details say FNB but my money is paid to ABSA. I feel that discovery couldn't help me at all and I am not even sure if they will pay me back my money. This such disappointing to me as a customer for so long, I will never take any insurance with discovery again I feel hurt and I want my money.
