Poor Customer Service, or Lies?

I got a 5G month-to-month and cancelled within the first few days because of poor coverage. I have been told I will be refunded the rest of the money and have been waiting since July. The agents do not answer my calls, and when I wrote a review on this very platform a month ago I was told a refund was processed and will reflect within 7 working days. Lo and behold, it has been more than 7 working days and I followed up with Rain only to be told they will be in touch. I don't know what's worse, the poor customer service or the lies/false promises I am told and given?
