Premier banking - no responses to emails

FNB Premier Banking, have the "banking team" to attend to your queries within 24 to 48 hours. I have sent mails to banking suite since before March month end, to downgrade my account back to Gold status. Premier account promises all the additional benefits, with a monthly fee of R185. Not one of my mails were responded to, after now 5 emails, and still not one has been responded to. I physically went in to a branch yesterday to sort this out. Of course, now my account is overdrawn, as all the fees were knocked off immediately, this too was not discussed with me before the downgrade. I wanted the downgrade done before month end, to pay the lower fee of R105 per month. They took off R185 the end of March, and now again more fees. And now there will be interest on the amount overdrawn, until i deposit these funds. I am very disappointed with the service from FNB "Premier" not one of my queries have been attended to, all the same query. Had this been attended to, on my initial enquiry, before end of March, my bank charges would have been R105 I am considering moving back to Standard Bank
