What should I do if I always receive natural gas text messages?

Hello, landlord, if your mobile phone has been receiving the payment notice from the gas company, then in this case, there should be a user using the gas of the gas company and then leaving your mobile phone number when handling the business, which leads to sending you short messages frequently, but the other party does not know the arrears. Or maybe your mobile phone number was used by others before, and then you handled the natural gas business, and so on. Therefore, the gas company will always send payment notices to this mobile phone number.
