Vodafone India — Non resolution of complaints made by me

Respected Sir, My complaint is regarding Vodafone mobile app, numerous calls have made to vodafone customer care regarding this. Problem started while paying my monthly bills through vodafone app, after entering proper credentials and while selecting internet banking after entering proper otp with my password, the success page was blank.Though money was deducted from my bank but i was unable to know whether my payment was successful or not because success page was blank. Regarding this i had called on 4th march and asked them whether they received my payment as i couldn't know because the success page was blank. I also complained them for the app, that time they told me they would forward it to concerned department. Next month on 4th april again i faced the same issue, while paying my postpaid bill through vodafone app and entering all the proper credentials including otp and password, the page got blank and no success page was displayed. Again i called to verify from the vodafone customer representative whether the payment is successful or not, they told me it would take 24-48 hrs to reflect payment. Then i again told them that it was 2nd time i am facing the same problem and asked them about the resolution of my previous service request. He told me your case is closed. i asked him how the case is closed when nobody from vodafone called me or informed me. He again generated one service request number ([protected]) and told somebody from the dept would call me. I asked him of my previous complaint ([protected]). I couldn't get any answer from him. Today i again called voda care, asking about resolution of complaints, the answer from the executive was there are no complaints made by me, i again told to see properly, she told me there are no complaints, i gave her the service request number, then she said yes i can see one complaint, i told i have made 2 complaints, then after some time she said there are 2 complaints, I asked her how she was unable to see my complaints on a single desktop screen i asked for their resolution she said they are resolved. I asked for any other from senior team, she kept my call on hold for more than 10 mins and later told me manager was busy. I had realized this is such a pathetic state of service and for me this has for the third time, which no one would expect such crap answers.I was only expecting my problem to be resolved. Thanks Yash
