There is no power nor strength except with Allah

Peace be upon you. They called me and told me they are from Sofac company and asked me to pay my credit. I said I did not borrow anything. Then they told me if this is your phone number, send us your national ID number and your contract number. I sent them my national ID number, then I asked what they did, and I did not give them the contract number. They started bothering me daily. The number that bothered me starts with 0520.
