其實你是因為套片裏面常常出現走面而失望，所以你可以這樣說：
I was very disappointed at the movie and annoyed by the off-key sound in it. At first I thought it maybe the sound effect, but its continual(continual與continuous不同，continual是間斷，而不是不斷） occurence convinced me that the tape was possibly corrupted.
Since I do not want to spend time on this problem anymore, I am now expecting an immediate and full refund. Besides I am going to(是打算的意思）tell my friends and family(其實用others代替my friends and family更好，因你不需要向他交代那麼詳細) about this awful experience.

I was very disappointed about the sound effect of the entire movie. It was out of tune. At first, I thought that really was the special effect, then this sound problem repeated again and again. It seemed like the tape was corrupted.

I did not want to spend any more time to tortune myself, therefore I got up and asked a full refund for my ticket. I will tell my friends and families about this awful experience.

Correction
"I was so disappointed about the sound which was out of tune frequently from the begining to the end of the movie. First of all,I think it may cause by the sound effect of the movie, but it repeated in a short period of time frequently, It sounded like the tape is being interrupted."
呢部電影的音響效果由始至終都另我好失望因為成日走音.開頭我以為呢d只係電影嘅特別音響效果,但之後d音響效果重復又重復,而且好朋密.d 聲好似d錄音帶走音甘.

"Because I do not want to spend any more time on this problem, I expect a full refund immediately. I will be informing my friends and family about this awful experience.";

個begining,corruputed串錯字
It 要細寫

At first I think it might be caused by the sound effect of the movie, but it repeated in a short period of time frequently. It sounded like the tape had been being corruputed.

Because I do not want to spend any more time on this problem.
[I am immediately(?! not clear)] .
