Are the gards always useless??

I was assulted on the 3rd of July by 3 guys in a bright daylight and got a broken nose. One of them was carrying a metal bar and luckily jost got beaten in my body not my head with the bar. My partner took a picture of the car's reg number. She contacted the gards straight away and drove me to the hospital. 2 gards showed up in the hospital taking statement and reg number and all that. I was told I would be contacted within 2-3 days. But the only thing was a letter from them saying it was reported and the name of the gard in charge. A week passed by no calles. I tried calling and talking to her but she was never in. Eventually my partner got to talk into her 10 days later when I was in the hospital having surgery on my nose for that assult. She said she would call the following day to come and get a statement. Statement??? Yes she said they had to get another statement, a formal one and they could not do any thing with only the reg number.

We were waiting for her call yesterday nothing (eventhought she said she would be in all day) called the station many time to talk to her but nowhere to be found.
