Telkom tells me I must phone back on the 4th

For the month of Jan 2016, Telkom has invoiced me R415 instead of my usual R299. This morning I decide to query, get put on hold for 10 minutes, then i'm told they are transferring me to account queries. Waited again and nobody answered.<br> Then I go on the chat, I explain and this is the reply I get:<br> \Then reason why Im asking is because we are unable to resolve any queries relating to your latest Telkom Bill at the moment. Unfortunately our systems only update on the 4th of the month. We apologize for the inconvenience, for your queries to be resolved to your satisfaction, please contact us again on the 4th.\"<br> What a ridiculous response that is. STuff you Telkom.<br> "
