Vodacom multiple enquires on credit bureaux for a single application

Why does Vodacom make more than one enquiry on your credit profile when applying? Last year in October I went in-store at Canal Walk to upgrade my daughter’s number. Vodacom made 4 enquiries for that application. This year I needed fibre and app**** online and later spoke to a consultant. Later I find out that 4 enquiries were made on my credit profile. Vodacom you do realise that enquiries reflect badly on one’s credit profile and lower one’s score???
