Forcing me to do a credit check for a loan

Every time i go to a branch to sort out an enquiry or an issue , almost all the consultants i visit whether in Umhlanga or Verulam FORCE me to do a credit check to see if i qualify for credit. in the Gateway mall branch i requested so many times on the 28th of January that i don't want any credit, she still put it through, another incident happened another lady called her supervisor to advise me to do a credit check to see if i qualify for credit or a loan and says that it is a requirement. Let me know by replying to my review so i can show them this . Its against my interest and will and i will close my bank account or call the ombudsman since the only excuse they can provide is that it doesn't affect my credit score, i don't care what you'll say , i don't want any beat around the bush when i go to any branches and waste time and if i don't want a credit check done , you'll cant force me
