Terrible service!!!!

I moved overseas and no longer wish to have my cheque account with Investec. So I requested to have it closed. After requesting to have it closed, I have received a 'settlement balance' for the closing of my cheque account? Have you ever heard of anything as ridiculous as this? So I transfered money from my overseas account, and then I received an invoice of R150 for the tranfer of money into my account? To top it all off, I have followed up on the closing of my account and no response as yet! You're pathetic!!!!!
