Why not tell them not to call Again?

this sounds very frustrating. If they are calling while you are t work it may be worth telling then a specific time to call back,. and thn take the time to explain that you are fully vaxxed, to flag up the ridiculous number of calls and to ask them to take steps to correct the record. 
If it is a genuine number the other possibility might be to call it yourself, when you are not at work, and explain the issue. They may be able to take your name off their call list, or alternatively, if it is a cloned number, and is a scam, then they may already be aware and can tell you (and then set the ring tone to silent and ignore it)
