2months later matter been not resolved

I received a phone call from one of the vodacom consultants end of the February offering me extra benefits for less cost. I did confirm that no changes on my existing deal as it was always open end just more value. To my shocking surprise I start receiving sms informing me that i am out of date. I travel a lot and need my calls and date always be available. I imidiatly contacted company and been informed that changes were made to my deal which i did not agree or gave permission. I was informed that consultant spoken to the supervisor and I didn't need to worry everything will be fixed. To my next shorking experience R2961 wad didacted on the 7 of April. I immediately contacted vodacom and as usual only empty promises apologies and stories how my matter been escalated and how soon it will be reserved. Last call i received last week informing that my matter been investigated and will get feedback soon. 2 months later because of somebody's unprofessional behavior I am still waiting for my refund and paying much more what I use to pay. I am totally disappointed and discussed with the service if one can call it a service being provided. I've been with vodacom for the past 22 years and feel like I don't want know you anymore and would like to cancel all my business with you. Hope after 2 months I will finally get some answers.
