I want to know which of these two sentences below is correct both grammar and meaning wise :
So many appliances in our apartment had been broken down and then got repaired
OR
So many appliances in our apartment had broken down and then got repaired
I prefer the first sentence because passive grammar is used in it , and I should say that I have an IELTS exam in less than a month and I want my mistakes to be corrected , if here is not the right place for asking such questions , let me know please.
Thanks.
