So happy for you. Only those who have been like you can understand. Indeed sometimes you just have to surrender to God. In my case I got a response every time I complained via the feedback in immi ac. Last response was that they were not gonna respond to my complains again. I had complained as a suggestion once, complaint once and compliment last. Three times in total. I also complained by email and was responded by generic. However, when the CO contacted, she quoted my complaint and said I had not provided evidence of what I was talking about so was told to attached requested information. After my last complaint, as a compliment and being told off, my Grant came a week after.
