Back Pay Deposit Timeline

I spoke with an agent at my local SS Office, the rep said he was processing the approval and moving the claim to the pay center (this took an hour) but he was doing it with me on the phone. He completed the call with all the details carefully outlined (older Gentelman) he knew what was up at the What's Up. He said 2-5 max 10 days for deposit, went on to say I would get my money before the benefits letter. Its day 8, yes I know 2.6 years of worry and I am jadded. I called the office today to make sure my records reflected his comments and the rep told me 60 days! Who is RIGHT?
