REFUSAL TO ASSIST ME WITH CONTRACT CANCELLATION

I have been to more than 5 Vodacom stores on more than 15 occasions in seek of help cancelling my contract. Not because I want to cancel, but so that I can pay it up and get another contract. The shops will not deal with me as a corporate customer, the call centre is useless and slow, it has taken me months to get the quote for cancellation and now the service consultants refuse to give me the necessary information I need to make it effective. They have also refused to give me their contact numbers so that I can discuss the issue with them over the phone, rather than email 4 or more times. I also have requested on 4 occasions that the signal booster in my home is looked at / replaced. I have not hear 1 thing back from the network and coverage department. Why is telecommunication service delivery so bad that we have to complain for something to get done. Its so ridiculous. I need someone from management to contact me that will actually give me the answers I need to resolve this.
