I am reaching out to express my dissatisfaction with the absence of communication and assistance

I am reaching out to express my dissatisfaction with the absence of communication and assistance. I have been anticipating a response to my complaint, but I've received no feedback or updates. I am writing this because I am experiencing unfair treatment, and this circumstance is profoundly unjust, unacceptable, and demoralizing. I was asked to return the home router and received assistance with the cancellation, but I was still billed for a month; please reimburse me I've been calling for a month with no assistance. It's been two months and im still waiting for my money
