No statement received, endless hang-up calls from “Lancet/Lancet Collections”

I have never received a statement from Lancet (by email or post), yet I keep getting repeated calls from rotating numbers in the +27 51 110 25xx range. Most calls hang up immediately or are silent. I submitted an online enquiry and sent an email asking whether I have an outstanding amount and to please send me a statement—no response at all, other than more calls that hang up. On one occasion someone answered; I again requested a statement. Still nothing.

This is frustrating and unprofessional. If there is a balance due, send me the account statement with dates, CPT codes, and payment details so I can settle it. If there isn’t, stop calling me. I’ve attached a screenshot of the call log as evidence.

Desired outcome: Email me the full statement for any outstanding balance; Confirm receipt of my contact details and preferred communication method; Cease automated/blank calls immediately.
