Worst service ever

Vodacom is the worst service provider being a loyal customer for over 8 years and having to call them a 100 times to cancel a contract is totally ridiculous ... I was told to cancel a contract via a 30 day notice period and I did call on the 1st of feb to cancel spoke to agents advised the contract was cancelled however I did not receive any notifications so I called just to be sure and check if agents did what I asked to did little did I realize the agent was unprofessional and *********** they advised that the contract was not cancelled and then I canceled again an again ... I asked to speak a manager the agent advised she cannot transfer calls and the manager can’t speak now she said she wil get the manager to call me I requested to times however it’s nw over 1 months and I’m still waiting I want vodacom to check call recordings ...now that being the 1st of the new month for my satisfaction checking to see if my contract has been cancelled its shows that’s it’s not cancelled it’ shows how *********** these agents and Vodacom is ...very very disappointing I also had contracts with other service providers and did not have a problems cancelling via telephonically
