Telus Callback to Landline

The exact same thing happened to me on Thursday. I called the 1-888-811-2323 number around 11 am and after few minutes answering the automated questions I was told it would be about a 60 minute wait to talk to a Telus CSR and was given the call back option which I gladly accepted.  After about 45 minutes I got the call back and was told to press " 1 " when I was ready to talk to a Telus representative. I pushed " 1 " but after about 5 seconds I was told that I didn't press " 1 " and to try again. This happened 3 times before the call was disconnected. I then called the same Telus number and once I got past the automated questions I was told that my number showed that I would be getting a call back and if I wanted cancel it. I didn't know that Telus makes a few attempts at call backs before giving up. So I hung up and waited for the 2nd call back attempt which came after about 10 minutes but once again every time I pressed " 1 " it wasn't registering. At this point I was thinking " screw this " and was prepared to try calling again on Friday. But then I got a 3rd call back about 15 minutes later and this time when I pressed " 1 " I was immediately connected with a Telus CSR. I told him what had happened and he said that he had never heard of that happening before. By the way - I was also receiving the call backs on my home phone so there might be something up with Telus call backs to landline phones.🤔
