Vodacom is useless

Yet again Vodacom has disconnected my account unfairly. I started receiving smses stating my account was in arrears on the 13th of October 2017 and i immediately emailed Vodacom informing them that this is a mistake and attached my proof of payment for them... even after numerous back and forth emails warning them that i am receiving continuous smses stating my account is in arrears and explaining that it was a mistake and they should rectify it before my cellphone is disconnected, and yet my cellphone was disconnected yesterday afternoon, I sent them my proof of payment 4 times between back and forth emails, this is the second time this has happened and i have had it up to here with this useless service provider. Since i have received my contract i have only had problems and issues!!!!!! I want my phone reconnected today still or Vodacom can arrange a courier and come and fetch this phone and i want my contract cancelled.
