Loop Mobile — Delay in converting from postpaid to prepaid again

Address:

Mumbai City, Maharashtra

Sir,
I was having LOOP Prepaid Number: [protected] then Before 5 to 6 months I have Converted into Postpaid But Iam not satisfied with the bills... I cant Bear it, , I had Visited Loop Gallery and given the request that I want to Convert my Number into prepaid again... they accept my request by giving Some Request No. After that I Didnt get any Call for the verification.. But they are saying that My phone was switched off when Verification Dept. had called me.. This is really false statement.. because.. I had not got any Notification about any missed calls...

Please sir help me to convert My No. into Prepaid again... This is my verry old No. and I dont want to disconnect it..

Thank you,
