overseas telemarketer supposedly selling home content insurance

Asian (Chinese) female voice. Has called before. Pretty obviously a call centre, as there's background noise, & it takes her a few moments to respond to me. (Presumably going through a list, & surprised when she gets an answer.) She has definitely called previously: 1. Voice is recognisable.
2. She always mispronounces my name in the same manner.
I use the latter as excuse to tip her off. No I'm not Miss Ah-nee (mistaken ID - I'm Mrs Anne,) but I don't tell her that. I just infer that she's got the wrong person.
I then tell her in v definite terms NOT to call me again, adding that I know it's not the first time, & hang up!
