Buy from them and look forward to never ending harassment

I bought a product once last year and made the mistake of giving them my cell phone number for delivery purposes. And since the harassment has not stopped. They call almost everyday, I have asked, pleaded, begged, spoke to mangers and asked to be removed from their database and stop with the calls. Nothing works they just change their number and keep harassing. Not really sure if someone has thought this strategy through, as even if it was the last place open during a lockdown scenario am still not buying anything from here. This is the result of their harassment hopefully aligned to the objective they set out to achieve, if so good on them given the lack regard for their customers or in my case accidental customer never to repeat the same mistake.
