Home lone refund

I had a bond with FNB H L on the 21/08/17 the bond was registered to a new owner. Them FNB deducted on my account on the 31/08/17 again on 07/09/17 when I call the told me I will get a refund of R 11 518,04 to my account I waited, then on the 28/09/17 I got half of the refund. I call to ask when is the rest on the one will it be paid I was told on the 20/10/17 the day came and passes I then called after few day to get if I was told to wait for 48 hrs I waited nothing happened I called again I was told to wait 48 hrs. I keep on calling till 12 December 17 when I was told that the money was payed to my partner on the 28/09/17. I then ask why I was not told this the first time I called to one cold tell me. The thing is I being paying this bond alone for two years now the refund is being payed to someone who did contribute. I then ask for all the documents that fnb used to pay out the refund the could not send the documents to me now I siting without any one helping me. I so disappointed to fnb home lone call center operator it look. I want the documents user to claim so I can take action according
