Terrible service

I have been struggling for 4 weeks for dstv to upgrade my account and put me on extra view, instead they have downgraded me and i had to pay extra amounts to fix the problem,every week they switch of my account and have to struggle to reactive it as they blame it on system error,they refuse to put me through to a supervisor as they put me on hold straight away,for about 45min at a time ,finally when they take me off hold i am told ,they will contact me back within an hour and sort out the problem out of which they never do and each time i speak to a different consultant that has no idea what is happening with my account, they now are unable to put me back on extra view due to a system error and have opened two accounts without my go ahead ,the service is absolutly terrible and i am very dissapointed and unhappy
