My taxes were accepted 02/12/2021 and I still don't have my refund. The WMR tool was showing "accepted" and as of 03/16/2021 still accepted. Anyone else have this issue?

I don't have any of the exemptions that would delay my refund. It has been stuck on accepted since 02/12/2021 and now the only message I get is "your tax return is still being processed. A refund date will be provided when available." I have tried for weeks to call the IRS and they aren't accepting phone calls. Anyone else have this happen to them?
