Vodafone — I beg you for the service

Please yaar I am pissed off with your service. I m not able to hear anything while on call. I thought there is prob in my phone, but 5 people are using vodafone, everyone is getting same problem, there is no support from you, if the concern is not resolved in 24 hours then will raise port request, I will escalte to next level.. such a ### netwrok. In mail and complains in app are useless no support.
