Poor service rendering

I have contract with vodacom for 2 decades.my nightmare begun when I shift to online service.Most of the Agent are croocks.They will lie to you to get new contracts.I dont know how many times I cancelled the contract and it has been renewed.When requesting help you will be reffered to a robot called Toby. EVERY AGENT has his own answer.I regret using on line service. They will take you from pillar to post using fancy word like migration !Our conversation are recorded but when you refer to them nobody cares.My cotract keep on pilling up no cotract send by email so as to refer to.When needing copy no one is interested.I will never renew my contract with them again .I am done. I dont know when last did I get a new phone from them .Except on Apple contract
