How refunds work

I have absolutely nothing from bulb about my refund .
I have no emails or no answer here at all .
My topic merge with something else.
There is no direct communication with Bulb.
6 + months I am trying to communicate to receive my refund which is more than 1000 pounds now. I am a single mother and struggling financially due to my long Covid ilness.
Can Bulb sort out one person refund ASAP ??
