vodacom has no manners

Not only does vodacom spam phone me to sell me fibre i dont want, when i politely say, no thank you I have fibre already, i get cut off, not a thank you for your time, thank you for letting us waste your time, thank you for not being a **** about me phoning you with a spam call, nope they just put the phone down. Thank you vodacom for your manners.
