Double billing!!!

I posted a complaint on Oct 5 and received a reply, stating that someone is working on my complaint and will be in touch shortly. In my original complaint I mentioned that I would be out of the country from 10 Oct and that I should be contacted before then. Well, my problem has not been resolved and no-one has contacted me. I really don’t feel like repeating my complaint - the short and tall of it is that I have renewed my contract and now my October bill shows I am being charged for both the old and the new contract concurrently. I have also received the minutes and data for both, which I do not want as I am out of the country for the rest of the month. Listen to the tapes: the guy that signed me up for the new contract clearly said it would take effect from 1 Nov. Either way, it is clearly wrong to have the two contracts overlap. Furthermore, I logged two tickets with Customer Care and both were closed, also without contacting me and without resolution. The latest one advised via email that I can claim my money back after the bill run. What utter madness?!? NO NOT TAKE MORE MONEY OUT OF MY ACCOUNT THAN YOU SHOULD. I am currently out of the country. Contact my via an email address to which I can reply DIRECTLY to the sender. My mobile number is not working here.
