PLEASE DO NOT USE STUDIO. I ordered a 2 in 1 tablet for my child's Christmas on the 28th of November. I was told GUARANTEED delivery for Christmas. I paid 80 in full when I ordered. I called them yesterday to ask when it will be here and was told the 28th of Dec. I told them this was my child's main gift from santa. The woman I spoke to said if I cancelled this and ordered the same model in black it would arrive in time.i reluctantly agreed she then told me I would need to pay a further 60 pound as my first refund would not go through straight away. I thought maybe 3 to 5 days for my refund. After taking my new order I logged on to my account to see she had ordered me a completely different tablet. 4 phone calls later and 140 pound of my money in THEIR account I'm told even though its their mistake I can't have my money back and need to wait on the 2nd tablet to be delivered then sent back to get my refund. I am a single parent and have no main gift from santa to give to my child. I am heart-broken. Please Do Not use Studio.
