keep getting disconnected yet i paid and am placed on hold fr more than an hour

Smartcard: *** I have been invoiced on 7July and made a payment on 6th for the month. I called on 6July to be reconnected and after being on hold for 30 min was reconnected. On 12Jul I was disconnected, i called the useless call centre again and they told me the previous agent reactivated an old decoder so they invoiced me for that, after 1hour and 10 min on hold without the agent even coming back to advise they are still sorting the matter I was reconnected and assured this wouldn't happen again. Guess what I have been disconnected again today and after being placed on hd for 30 min without explanation as to why I wa disconnceted I hung up. No-one bithers to call you back /sms/watsapp or email you to resolve the query - you have to pay for their useless service and spend hundreds of rands calling to rectivate a service that should be active. Again my kids are without TV while I try to buy more airtime to be on hold for service I should be privy to as a paying customer. I AM DONE with multichoice!!
