because this is your operator's problem, in my country there are 3 mobile operator's, one of which used to have problems receiving sms, months ago for example I could not log in to my blockchain.info account because I did not receive the sms with the verification code and even with binance it was the same thing and I had to change operator to be able to receive the code, what you should do is wait at least 3 days because sms usually arrive only that it takes a long time, at least in my case took 17 hours and after I received the code I immediately changed operator


as expected, these exchanges do not have a sufficient number of staff to handle support tickets, and customers always have a problem with no solution for many months
