Major problem with reversing data costs

a data bundle was purchased in error, I requested the reversal of this on the 4th November. Data was gladly reversed but I was told the charges would only be reversed on the next billing period ie December.<br> Second 3gig data bundle purchased but only 5meg allocated to my account! Charges not reversed! Job logged on the 6th November.<br> I still await feedback. Every time I call the 111 number I have to firstly wait 2mins through the voice prompts before I reach an actual person. If my calls don't get cut off, I deal with *********** people who simply have no answers to my problem! Over a month later and I am still fighting to get this problem sorted out. On bundle apparently credited but this does not reflect on my statement! I refuse to accept to wait any longer for feedback! Someone needs to sort this out today!
