Vodacom has a stuff you attitude to customers and will not fix issues they create

I purchased a pay as you go sim card from Vodacom to be used as a second number. It turns out to be a recycled number(they recycle their numbers). I am getting all kinds of SMS's from banks for withdrawals, loyalty messages, notifications as to study guides and other information as well as spam calls and SMS's. This is obviously related tot he previous owner of the number. This is apparently a standard for Vodacom to recycle the numbers when they become dormant (they are obviously not doing it correctly). I have asked Vodacom to reissue me another number that is not active and they have said they can do nothing and I must live with the problem or purchase another pay as you go. This is unacceptable and unprofessional. I did not ask for a recycled number ( that was still receiving the information)and they issue these to pay as you go and contract customers. According to them and if there are issues tough, pay for another one (the only solution). My recommendation is with this attitude no one should use Vodacom if this is the lack of professionalism they portray. I will be throwing the sim card away and going to MTN to get a new pay as you go sim card. I cannot understand how Vodacom ever hopes to be judged as a customer caring company with this STUFF YOU attitude. Shame on you Vodacom I hope you loose many customers due to this issue. You created it and you will not fix it. You do not deserve to be a service provider with this attitude.
