AVOID LIKE THE PLAGUE!!!!!!!!!

Whatever you do, do not purchase a Prime card!! It has been nothing but hassle from the start, and the call centre staff are useless!!
I bought a card last week for my mums birthday, thinking it would be a great and convenient way for her to buy something special. Didn't know the amount I wanted to put on the card as it was shared between me and my brother so just paid the £5 for the card and put the minimum £10 on it to activate it...as it says you can upload it online. Tried to upload and was told I had to upgrade the card first, which was going to take 3-5 days (not sure if this was on top of the 3-5 days I was told the registration would take). Very helpful customer service told me this (note the sarcasm here).

So I thought, I know, the amount to be put on the card has been decided now, so I'm quicker just buying a new card, paying another £5 fee and putting the full gift amount on it, as then I'd only have to wait the registration 3-5 days. Did this, and then tried to register the new card only to be told that because it had the same mobile number on this registration as was on the original that it couldn't be done!! Called the helpful customer service again, to be told that they would now need to send this off to Prime HQ to see if the "block" can be removed on the registration. Oh and that I might have to provide ID and address verification for this to be done!!! I currently have to wait 3-5 days before they decide if they will lift the block and whether I am going to have to provide ID etc.

An absolute joke, the one time I didn't do my research on product reviews and I've been completely bitten in the *ss :( If any has any suggestions as to what I can, all options considered!!
