Dear Sir or Madam,
I am writing (in order) to complain about the package holiday which
had has recently been organised
recently by your travel agency and
to suggest some solutions to the problem(s) (I've enccountered).
When
me and my friend my friend and I reached the destination, it turned out that there was no twin room avai(l)able in the hotel (which I had booked before). Instead, we got (were offered) a double room, which was very incoventient for us. What is more, the food did not meet our expectations
., as our meals became (were becoming) a routine – we were served with the same dishes every day – toasts and juice
on for breakfast and supper! I was very dissatisfied (with it), as on your website you assure your customers that your menu offers various and fancy food(s). I wanted to speak to the manager, but he refused to listen to my complaints.
After that, so we decided to (check out and ) look for another (other) accommodation.
You
deffinitely certainly need to pay more attention to requests of your customers to avoid further misunderstandings. I also strongly suggest that you
to hire a professional chef or simply change (adjust) the description (details) of your offer on your website.
Without changes like these If you do not follow my advice, there is a strong likelihood that you will lose
definitely your customers. Also (Finally) (it goes without saying) it is obvious that we would appreciate a written apology.
Yours fairhfully,
