fruad / poor service

I received an email written quote for upgrade from Vodacom i didn't respond to the the email. 2 days ago i decided to call Vodacom just enquire why was R85 deducted from my account and the R489 I was informed that i upgraded my contract took two Nova 13i phones and never agreed t anything it was upgraded without my concern. call center informed me that it was done it the store chat connect at horizon yesterday i called chat connect head office and the lady assisted me to get information of the store and their contact numbers . i called the shop after i was informed that it was done in their shop by Nelm M i spoke to NelM M she said she still with a client she will call me back she didn't then i called the head office again they said i should call the shop request to talk to the manager i spoke to the lady name is Nela i explained to her what happened and she said she will talk to Nelm to find out what happened she promised to call me today at 9 am she didn't give me a call i then called her around 12:45 pm she said the upgrade was done online and she have a recording of me agreeing to the upgrade i requested that she send me the recording she said she still going to check if she is allowed to send it to me i asked her why would it be a problem because if i did it on recorded line client has the right to be given the recording according to CPA act. she said the upgrade was done by Thando but when i went to the Vodacom shop they said it was done by Nelm M i feel like the store doesn't take me serious and they are trying to shield whoever did the upgrade . its been 3 days now not getting any assistance she said she will have to investigate who accepted the phone when i asked her how long will it takes she said she cant tell me i told her the business have SLA so she should provide me with SLA time she just kept quiet on the phone am so annoid and frustrated because this is my credit profile they are tempering with and they are not treating my case with sense of urgency i want the superiors from Vodacom and chat connect to solve this i want this contract to be canceled and am no longer interested in doing any business with you guys the service i got is very poor from call center to she stores. call center says a different story the store is telling me another thing so am done please cancel this contract. .
