If you think Vodafone's billing system is bad, wait until you become a 2degrees customer

So I signed up to 2degrees' $55 plan, one for my wife, one for myself on the 30 March this year, because they were doing a promotion for 50% off for six months during the Easter weekend.

During the sign up process, the sign up page did say the discount may not apply until the second bill. I am OK with that.

The first bill was in fact non discounted, no problem. Second bill arrived today, full price again! $55.

Just called 2degrees, explained to the gent that both me and my wife are having the same problem (a bill of $55 each). I explained to him that I signed up on the 30 March with the promotion, and I asked to have this month's bill regenerated, with the 50% discount, and I will pay the remaining 50%. I also asked him to make sure the remaining discounts will be applied automatically, so I don't need to call (and listen the same music again).

--> funny thing about the music, part of the lyric said "we are back to square one". This does sound like my current situation.

The gent said this cannot be done. He needs to forward this to another team and they will apply the discount in a few days time, so my next bill will have the first discount. And I have to pay this month's bill in full.

I explained to him this is unacceptable, I was promised the discount will be applied from the second bill, at the latest. I do not want to wait till the next month for the discount to be applied (who knows whether I will have the discount applied in the next few days on next month?). And with customer service and/or billing system problem like this, I want to get my six discounts ASAP, so I can switch sooner if I want. Don't want to wait an extra month for this.

@2degreesCare , can you help? I believe among Spark, Vodafone and 2degrees, you guys should have the latest and greatest billing system at your disposal? How come you cannot adjust a bill that was generated with error by you guys in the first place? And insist the customer should pay a bill with error?

Also, I ask the gent to email me the case number / reference number for my case, and my wife's case. He said this cannot be done and I need to write it down with pen and paper.

@2degreesCare, please help.
