From the day Vodafone had upgraded the network to the 4g network I had started to face the network issue in my locality, there ae many people who faced the problem in our place the vodafone people are not at all concerned to the matter as many time we had complained the vodfone customer service as well as the vodfone showroom people bit no body responded then we are forced to Port our numbers to other network, vodfone has no customer service.
