Payments received but line suspended

I have paid an amount in cash on the 25/05/2015 and a deuction went off my account as well on the 26/05/2015. My line has subsequently been suspended.<br> <br> I have contacted the call centre who confirmed that payment of 25/05/2015 reflects but bot the deduction of the 26/05/2015.<br> <br> I have mailed proof of payment. but is now advised that my service might possible be unsuspended by the end of the day or within 24 hours and I just have to wait until someone gets this done?<br> <br> Why am I inconvenienced if it is your system that does not update incorrectly? Why in this instance can the service not be resumed immediately if you have all the documentation requested?
