LACK OF PROF

I have received sms saying i gave concern to check my credit affordability and i dont know this people, then next thing i receive a whatsapp call , their back ground was veeeeeeerrrrry loud and i told this lady that i dont know you people and what is this???? the lady coulnt explain to me and gave the phone to the guy who said they are sorry , but while on a call i received the same SMS from them with the diff id nr....i am just so angry for playing around with my ID number and where did you guys get my personal details because i dont have any debts. THIS COMPANY SHOULD BE CLOSED OR THEIR EMPLOYEES THEY NEED 100% PROPER TRAINING. I AM SO ****ED OFF 😡😡😡😡😡😡😡😡😡😡😡
