Account not closed after more than 2 weeks

I requested and received a settlement letter for R362,650.15 on the 16th January. This had to be paid before the 24th April. On 15 April I paid R32,650.15 into the account and on 17 April the buyer for my vehicle paid the remaining R330,000.00. MFC have confirmed receipt of these moneys, yet the account still has a balance of over R10,000.00 on it. I took this up with Zakhele Meyers and on the 22nd April received an email confirming that this account had been sent for closure. It is now 12 days later and despite numerous attempts to get hold of Mr Meyers telephonically I have not been successful in getting any help of this matter.
