Mammoth clock alarm

Brief silly text to practise my writing... an imaginary complaint to an imaginary eBay user:

Dear eBay user parakeet:

I am Francis Baratheon (AKA "mockingbird" on eBay) and I am writing to you about the item "Mammoth clock alarm" that I bought to from you two   a   hundred and seventy five days ago. I have several complaints about this purchase, and they are:

Firstly First, ('Firstly' is ok, but 'first' sounds better) the parcel arrived to at my home with two hundred and seventy three days of delay. You assured me that it would be here in two days, but that was a complete lie.

Secondly Second,('Second' sounds better) the sound of the alarm is not a mammoth scream as I requested, but a ridiculous cricket sound. I don't like it at all.

Finally, and the most important: the volume of the ridiculous cricket alarm  it   is not 150 decibels at all. I tested it with my pocket-sound-measurer, and the result was only seven decibels. Another misleading statement of your ad.

So, as a consequence of your lies, I didn't achieve to wake up in time the day I had to take a steamboat to Argentina, because, of course, I didn't hear the cricket alarm.  I stayed sleeping too much slept in and when I arrived   to   at the port the only thing I could see from the steamboat was its fume over the horizon.

Therefore, I ask you for a refund of $7.500:$22.485: (this figure here is wrong. Because you have a ":" after it, it should be the sum of the following amounts and should be $15+$7.485) $15 for the faulty clock and $7.485 for the ticket of the travel I lost because of your fraud.

Waiting to hear from you soon,
Francis.
