Reliance Communications — Not getting full benefit on recharge of 123 Rs

On 9th Jan 16 I got a message from relaince communications that I will get 1 Gb 3g net pack for 28 days on my prepaid GSM number [protected] on recharge of 123 Rs . I made a recharge of 123 Rs on same day but I received only 500 MB 3G DATA. I made a call to relaince customer care but instead of helping me he asked me to call him after two hours, once again I made a call to customer care (Mr Neeraj) he also told me do the same and he just disconnected my call, there after I have sent an email to [protected]@relianceada.com on 10th Jan 16. Till date I haven't been benefited and didn't get any reply from relaince though I tried a lot..you r requested to do the needful at the earliest
