OVERCHARGING WITH NO REASON

I am utterly chocked by the way you handle your customers !!<br> <br> After taking a contract with you in June 2015 I have been billed with an outrageous amount of R4103.90 for PACKET SWITCHED DATA CALLS which I am still trying to find out what this is exactly, knowing that the only data I have used was the one I BOUGHT through FNB at R160 per 1GB or my workplace's wireless wifi.<br> <br> I did however call your customers line which cost me in airtime & was not helpful at all when I asked for an itemised bill. Besides, they even did want to charge me for a report, which I should get the FREE right to see !!<br> Finally out of despair, I did ask your agent to then get a cap on my monthly PACKET SW. DATA CALLS (which I still don't know what this is about !) but none of your agents could help me ! <br> <br> If you get this contact me so that I can put an end to my contract & make sure that all my database know how much of a ***** YOU ARE & your service is !!After weeks of contacting you + going to your outlets with no REAL help but more headaches.
