Home loan installament

On the 25th of march I transferred money to my FNB home loan account using a registered beneficiary from my bank .A few days passed and my home loan account was not credited(of which could potentially affect my credit profile) I had to make means to make the payment to update my account. I called in FNB collections department to query and only to find out that my money went to a suspense account, I was requested to email my proof of payment of which I did on the 28th of march and ever since then I have not received feedback as to when will my account be credited. I cannot be making calls now and then with longer holding time with my airtime and not recieving any feedback of some sort, when I called in today I was informed that the consultant who was assisting me the first time has been making follow ups on the matter without any success. We are encouraged to use access channels for transactions now and then but you guys fail to update your banking details on your registered beneficiary and now it is supposed to be my problem to retrieve the funds.I just want FNB to credit my home to an account or make a refund, please sort the matter out.
