I turned off the phone removed the nano SIM arnd 5-6 times, did reset the network settings later did reset the entire phone still the phone showed searching for network.When contact the customer care rep on toll free number from my office landline she told me my number is blocked due to technical glitch .I can visit any vodafone store an get a new 4G SIM...As per her i visit Vodafone gallery at Kalyan West Opp Rly Station wherein the lady assisting told me that i have re-submit the documents she cant do any thing. she said its blocked because its an old SIM..So the conclusion is Im i at fault for using Vodafone services past 5-6yrs...And my SIM is blocked because o[censored]r technical issues.Shameful..Is this is what Vodafone stands for ?????
