Bad service

Very bad service, I was called for upgrade on my current decoder now I'm receiving sms tonsay my acc6is in arrears, I email and a lady called Kajal tells me I have two accounts and one is in arrears...I asked why do I have two accounts of my current one was upgraded..I am beyond livid.. she tells me I must call customer service after lockdown, I call today a man answers, i start by telling him I am receiving sms without saying a word to.me he transfers to call, I was on hold for over 10 minutes and put the phone down...they waisted my time and airtime.
