BT business responding to complaints

[Spanisit]

Hi, I have been trying to resolve a complaint with BT business but they never respond to written complaints. Has anyone ever had a response to a written complaint?  This means I have to call each time and repeat my complaint over the phone to a call centre, only for someone to tell me only EE can resolve it and they're closing the case ARG! Obviously I've had this  same conversation with EE who tell me only BT business can resolve the matter! I'm going around in circles. Anyone know how to get a proper complaint response from BT from someone who is allowed to use their brain to resolve the issue?

No there is no way to have a formal complaint in writing. I followed their website sent two email for complaint in order to retain record, there is no reply. I spoke to a complaint team manager, I asked why there is no reply, she said that email is not in use

Thanks, I suspected as much but it's so weird to have a complaints inbox but to then not respond to it is terrible.
