Extra unnecessary service billing

I already emailed customer services and didn't get a reply after 5 days. The service I receive from TFG are terrible. Here is the email I send.<br> <br> First of all. My account communication preference is only email and post.<br> <br> I would like to know why I'm getting billed every month for COL.LETTER FEE - TFG Head Office and a SMS CHARGED - TFG Head Office? Some months I'm also getting extra charged for a PHONE CALL FEE - TFG Head Office? <br> <br> I've been paying my account every month and still you phone me about payments and the afterwords you're billing me R20, because you decided to unnecessarily phone me. What nonsense is this?<br> <br> Why am I also getting charged for sms's if I don't receive any sms's and if my preference is email and post? Another R2.50 extra I have to pay extra every month.<br> <br> And what is the COL.LETTER FEE I've to pay another R20 every month. If it has something to do with invoices being posted to me, please remove this feature from my account.<br> <br> Kind Regards<br> <br>
