My son doesn’t like _____________ of his Math teachers.

Mark the alternative that best corresponds to the main idea of the text:
Read the extract of a text written by a student. The proposal was to write a letter of complaint to the manager of a store where the student, as a client, had a problem when he bought something online. The teacher explained the task and highlighted that students were supposed to come up with a situation, explaining what happened exactly and how they would like the situation to be solved. One of the criteria for correction was grammar accuracy, since the letter is supposed to be formal:
(…) To my surprise, when I opened the box, I realized that it did not contain the cell phone I had purchased. I had already bought other items from Luke's and I had never had any problems before. I was really anxious for my new cell phone and I just could not believe it. Though, I write this letter to inform you about what happened and to ask you for a refund or for the correct item. I called the store, but nobody could offer me a solution. People were a bit rude and I felt very disappointed. Never before had I been treated that way, which is why I also ask for a retraction. I am aware of the good quality of the products you sell. I have been a client for about 5 years. I hope this situation can be solved soon.
Looking forward to hearing from you,
Yours sincerely,
(…)
