Worse service ever

I've been having a problems with Dstv about my account since 27 July 2020, I made a payment of R670 on the 27 July 2020, after I checked on their whatsapp service how much I need to pay. I've made the payment at a ABSA ATM, I've used the following no as ref as given on their WhatsApp service ***, now everyday I have to call them on ***, because I keep on getting E16 error on both my decoders. It's now really unfair I can't watch any television, they cost me a lot of airtime. My 2 Smart card no is *** and ***. Yesterday I've called them 6 times because *** was off, now today *** is off, they just can't give me a proper explanation, encarage you to use their Whats App service but it's useless give you incorrect information.
