Unalloacted Payment

I've made payment on my Dstv account on the 28 March 2019, at RTT installations in Cape Town, however on that day RTT contact DSTV advising them there is an error while trying to process my payment, Consultant at DSTV said the will allocate the payment which i made, since then i had endless problems with the finance dept allocating my payment as I've provided so many proof of payments that I've made that payment on the 28 May, Dstv finance has thus helped me by locating or allocating my payment, which in the intertrim they shouldve asked RTT installations to provide their income statement showing that they made the payment to Dstv in order for them to allocate it to my account, but literally ever week since the 28 March they disconnect me, then i have to call numerous times in order for them to reconnect. What angers me is that, DSTV is now making this my problem to allocate payment which the not following there job process properly, i'm extremely frustrated and very unhappy with DSTV service, i'm an account holder with DSTV for almost 8 years and this is the terrible service i'm getting.
