AWFUL CUSTOMER SERVICE

I called on 2/18/2025 to disconnect my internet service on 2/22/2025.  The equipment was returned to my local store on 2/22/2025.  Then on 3/3/2025  I was charged for another month of service.  I called again and the service was never disconnected.  I requested a refund.  Then I had to call again on 3/3/2025 and on 3/10/2025 and on 4/1/2025 and most recently on 4/9/2025.  I was told each time that the service was disconnected and the refund should be processed.  Unfortunately this never happened.  I was promised on 4/1/2025 that the issue was escalated and I would get my refund in 3 days.  Of course, this did not happen.  I called again on 4/9/2025 and was informed that the representative at the local store did not return the equipment properly.  Now I am being penalized for employees not knowing how to do their jobs.  I have to wait another 10 days to see if I ever get the refund I am due.  This is unacceptable.  I should not have to make 5 phone calls for the same issue and not get it resolved correctly.  The customer service department is terrible and no one there seems to know how to perform their job properly.  They all need to be re-trained!
