Can a few billion friends on the internet stop some sms spam (part 2)

Had a call from esporta tonight. I asked them to stop sending me sms messages. The girl came over all grumpy and rude when I said it wasn't me who had actually asked them to call me. Then she lied, saying that all I had to do was ask them to stop sending me text messages. I explained that I had already asked and still they kept coming. She put the 'phone down.
