I called call center executive yesterday but I did not received proper reply from him. Hence again today I called to call center again and start my conversation as below.
Me: Hi, My Name is XYZ and my problem is ABC
Executive: Sorry, you dialed wrong extension please dial 123
Me: I had called on that extension but I was connected to this extension. I had also called yesterday to that extension but did not received proper reply from your executive, Please transfer me to desire extension if possible.
Was my part of conversation was correct or do I need to have better conversation in any other way? Specially using past perfect tense. Actually I wanted to focus on past completed action.
