thank you. This is likely to be problematic in that there will usually be a condition of the contract that states that the contract could not be assigned by the buyer without permission of the seller. Of course, this does not mean that the seller will not grant permission, but he has no particular incentive to do so and if the seller refuses permission, your friend will need to be the individual goes through with the purchase - presumably using your money to do so.
If that is the case, you will need to consider having your friend execute a bare trust taking clear that although your friend is to be the legal purchaser out of necessity for the above reasons, the property entirely belongs to you in trust.
In this way, either following or simultaneously on completion, you can have your friend execute a transfer into your name. There will be no money consideration paid by you to your friend as on the above facts, the property will already be held in trust on your behalf and it simply on assignment of the legal title to you and hence no further SDLT would be payable. If there is to be mortgage finance this complicates the position significantly but I trust this is not the case and you are a cash purchaser.
in respect to your request for a phone call, I have not accepted the call request but it is probable that you have still been charged. if this is the case, if you drop customer services online, they will be able to arrange a refund:
