Wrong item specs

ORDER NUMBER : #***

I received my parcel and tested it immediately. I could not use the newly opened pack batteries and had to use the usb power cable. I am more than half satisfied with it and it comes in handy for me.

My biggest problem is this: When I bought this flexible keyboard from HiFi Corp, I also bought the necessary batteries (AA), as described on the adverti*****t, at another shop. To my calculated need, 4 x 4 packs Energizer AA rechargeable 2300mAh batteries. Here is the problem and I really do not know how the marketing or advertising person could miss it. The packaging notes clearly that it needs 4 AAA and not 6 AA as advertised. He or she got it completely wrong. I planned this journey of learning piano in the field very precisely but it came to a short and abrupt stand still because now I sit with 16 high quality rechargeable batteries with no use. I hope HiFi Corporation can resolve this issue so that I may be able to enjoy the item I bought for a good course.
