worst service provider

Hi I'm really disappointed with a consultants at that store as it was so quick and fast for them to sign me up for two contracts.but things turned against me when I had to claim insurance on my mobile phone,he mistakenly insured a modern instead of cellphone.then I went twice to them and they promised to call me,as went for the third time they were sidelining me as I'm not their client only to tell me that I signed a contract and there is nothing they can do.I regret the day I gave Vodacom my business cause I have paid for my service provider's mistake and getting an a big egg in a face for trying to fix that.VODACOM SUNNYSIDE YOU ARE THE WORST.?? ?
