Missing Payment not reflecting on my account

I am a Premier client with FNB and I logged a query with FNB on 4th February as my husband made deposit into my FNB acc on 29 Jan (like he has done for almost 2 years now); it was not reflecting on my account. I get told by FNB (4 days later) that the Missing payments department will investigate. I then get a call on Thursday 11 Feb to say that FNB cannot assist in tracking this payment that was made from Standard Bank & I need to go back to Standard Bank. So my husband contacts Standard Bank on 24th Feb & they tell him that the payment did go to FNB & we need to follow up with FNB once again! So I send email to FNB on 24 February to give them feedback & again proof that the payment did go off my husband's account. It has now been 7 days with NO response whatsoever from FNB!!! I sent a complaint via FNB website as well as another email to the consultant i have been dealing with on Monday 29 Feb and have still not heard a word!! I have been with FNB for about 20 years and the service I am getting is utterly unacceptable!!
