Horribly services from Vodacom

I am very very disappointed in vodacom have 7 contract with them . Lady call me after telling her I am not interested she keep calling said will safe 50%on my account. Then my account increase with 2k told them don't want it they must take it off after spending 2hour on phone lady said she revers it . 21March one of my phone's was ****** and ask Vodacom to block it they said they can only lock the SIM and can only blacklist phone on the 1ste of April , because I downgraded. On 26 March I called again saying they still use the phone but they can't help me I must wait for the 1ste . On the 2 April I called them again to blacklist the phone and confirm its done .advice me to open case at police stations and I did went back to Vodacom to make insurance claim.it was decline because of the delay in blacklisting my phone and SIM but I did call Vodacom to block it .this is horribly services I want my contract as it was before and want my insurance claim process. I will place this on social media platforms and take it to the ombudsman want my account sorted or cancel ever contract I have
