Amazon has transferred 29, 999/- to my account number [protected] on 22nd jan and till now i have not received the money in my account, even they have provided me the transaction number 494007 which is generated by RBI as they told me but i don't know is it valid or not but whoever is right till now i have not received even a single penny in my account, i have called SBI customer care more then 100 times and they are saying that they don't have any facility to charge dispute in SBI, they are hanging up the call and not listening my problem .i think charge dispute is the only way to locate the money where it is stucked in the pipeline of transaction, resolve my problem ASAP.
please do the needful.
