Caller: Call centre for Solar Panels and battery

I apologised to him because I struggled to understand him. He had a thick/ strong Indian accent as he answered the phone. He was from a call centre for Solar panels and batteries.
I told him I already have it installed, which is a lie, but he took my name off the list (supposedly). I have blocked the number. However, we genuinely have no idea how many telephone numbers for Australia are sold overseas!! We must thank our old prime minister, Scomo, for this treatment. We suffer a lot more now after he put this plan into place to help put money in the government's treasury (sarcasm).
