Airtel — offer not working

Address:

Ernakulam, Kerala, 682030

I recharged my airtel no with rs 3997 which is the international roaming pack for uae which includes 500 minutes (Incoming and outgoing) 5 gb data and sms. I recharged and got the confirmation regarding payment done and the offer is not yet active. I'm not able to make any outgoing calls to any number. I'm only able to receive incoming calls. No outgoing calls can be made. When i called customer care they're not ready to solve the problem. They are simply saying it is a technical issue and it'll get cleared soon. They're not telling a time about when the problem will get solved. They are not responding correctly and cut the call after sometime. They do not refund the amount not activate the offer or solve my problem. The customer care executives are simply playing and when asking for refund they won't do that also. Fraud service and fraud people.
