Telus App issues

Hi, my i pressed pay bill on the telus app and it showed to pay my bill to to one account number then .5 seconds later it showed me to pay the bill on another account. I payed the bill on the right account and a few mins later i checked the telus app it didnt show i have an outstanding balance, a few days later the app asked me to pay the same bill, i been on 611 every day since the 24th of june to get this resolved and they havent fixed it yet, the app also shows the monthly installment for the iphone 11 went through but now its asking me fir another payment, i screen recorded the secuity issue with the app, is there an escalation manager i can submit this to
