Called twice on evening of 25/7. also 04915 70622 earlier in the day. All calls intercepted by CallGuardan. Suspected scam.

Call from this number 24 July, approx. 6.15 p.m. I did not answer it. Another call at 6.46, I answered it, he denied having rung before. ‘Not trying to sell me anything.’ 'Wants to send me some free samples to try out'. Asian voice. Have had these calls before, so said I did not want any more. Quite similar to one I had last year from (02) 9636 6007. Would this be classified as a "survey" call?? It certainly is not a charity.
