Not Pure Internet joy

I originally requested my Mobile data package be cancelled in January with effect in February.This didn't happen.<br> <br> I then requested again in February and I was assured that it will be cancelled end February/ Effective March.<br> <br> In March I was billed again. I spoke to another person and he assured me it will be cancelled and the amount will reflect against my account as a credit. <br> <br> On each call made, I requested a invoice for this mobile package separate to the rest of my account. I was promised this will be completed, however, I haven't received anything to date. <br> <br> End March invoice did not reflect the credit. I did not make use of the data for the month as the representative assured this would be creditted. <br> <br> I received a mail confirming cancellation only today.<br> <br> I called into the centre again this morning and having held on the line for what felt like 15 minutes, the call was cut as it was time for me to be assisted. Very Frustrating <br> <br>
