Unsatisfactory service

App**** for an online contract on the 19th of January 2022. Waited for a month before i could doing a follow up. I have made more than 20 calls enquiring about my application, numerous escalations made for consultants to call me back but no one has phoned me, even the manager who was supposed to contact me, still nothing, almost two months later. How hard can getting back to me be?? I am very unhappy with the kind of service istore customer service centre provides.
