Incredibly unprofessional company

This company has been harassing me non-stop for months now. I spoke to a rep who promised to send me the statements I requested as I did not understand why I was being double charged on my account. I NEVER received the statements. I have paid the money already and just today between the hours of 7 and 12 I received 4 phone calls and 3 SMSs. Unbelievable how unprofessional these people are, the SMSs are not typed in a professional manner (ex. "Ur acc remain SERIOUSLY unpaid and ur liable for all penalty. Pay now to avoid penalty" an actual SMS I received at 10am 5 days after already having settled the amount).

Double and triple check before paying them any money, my experience doesn't seem to be unique and RCS is looking more and more like a ****.

Can the RCS please leave me alone now, I have paid tbe money, I owe nothing to you and I will be closing my account first thing in the new year.
