Complaint to TFL regarding bus driver

Complaint I wrote to Transport for London just now regarding a racist/Islamophobic incident I witnessed yesterday on the bus on the part of the bus driver...

"I witnessed an incident yesterday that smacked of racism or Islamophobia perhaps. The bus driver took on all passengers and closed the doors. There was traffic ahead so he waited at the bus stop. An Asian lady came (visibly Muslim, wearing a headscarf) and gestured for him to open the door and let her in. He did not. That is strange but overlookable. She stood there right beside the door and clearly in the driver's view for what must have been at least 15 seconds, though he would not look directly at her pretending he could not see her. It was raining slightly and the driver wasn't going to open the door so she stepped back to take shelter under the bus stand. Then, another man came running, knocked on the boor and bizarrely this driver opened the door without a qualm. The lady from before saw the door open and stepped forward to get in. The driver without doubt saw her and closed the door in her face. I was fumed but did not kick up a fuss on the bus so as not to turn this whole situation into a fight and trusting that tfl has procedures in place to deal with such blatant abuse of position.

Btw, I didn't get the registration number but the driver had a yellow card in front of him with the number 208 on it if that is useful.

I have experienced such behaviour myself once previously from a bus driver and did write a complaint. However, after a number of weeks and queries from tfl for further information I was told no driver I described matched my description. I will be extremely disappointed if this happens again and will look to take this to higher authorities, whoever that happens to be. Apologies."

Don't like to complain and especially don't like to see bus drivers abused (my dad is a bus driver) but what I saw yesterday was just plain wrong. Maybe I should have kicked up a fuss on the bus there and then?
