Vodafone India — No network issue

My vodafone sim card no longer works. It was working fine on saturday then suddenly it said "no network". Even today it still isn't working. I've tried checking with other sim cards on the same sim slot but the slot works fine. I've tried the vodafone sim card in another device but that too doesn't work. I contacted customer care and he advised me to replace the sim card but i will be charged ₹25. I just recharged ₹150 and ₹247 the week before. For no fault of my own, now i've to go through the procedure of procuring a new card, pay for it and lose whatever, data or top up altogether. I might as well just go to another service provider.
