Confused with Telkom Mobile billing

<p>Good Day,</p> <p> </p> <p>I received my new contract, and devices from Telkom on 27 May 2017 - which was already a horrifying experience.</p> <p>When I requested my billing statement today 29 June 2017, I am disgusted to see Device Subscription Fee (01 May 2017 -31 May 2017 ) FULL amount being charged to my account, when technically I only had the device in my possession for 3.5 days in that month.</p> <p>I find it extremely unfair as Telkom or its agents, do not tell you this when opening up a new contract - therefore NO ONE SHOULD EVER OPEN A NEW contract mid month or end of month, as you get double charged and not even pro-rata charged.</p>
