[Resolved]  Vodafone — i am not able to send or receive sms on my number

Dear sir i am facing problem with my vodafone number that i am not able to send or receive any single sms from my number. I am facing this problem since last 2 months. I have made call to the vodafone customer care three times but they only said that your problem will be solved in 2-3 days. But its almost 2 months gone but my problem didn't solve. When i send sms from my number it shows error code 69. I shared it with vodafone customer care executive but he also didn't solve my problem. Please look into the matter.
Thank you.
