Disgusted in DSTV services

In may 2017 dstv installer Ramon from ZER satellites assisted me in upgrading my services from compact to premium, he came to my house on the 28 May and said that he needs to call in and give a voucher number nd they will upgrade me , he called in and advised me after speaking to an agent that I need to pay R120 at our local spar and that I must give him R500 to pay on my account which I did, he than came back the Monday and advised that I must give him R140 to print my payment receipt and I gave it to him he came back that same week on a thurs/wed and advised that he needs R200 which I gave him R100 and than another R100 I then received an sms saying I owe R750 which I ignored as I gave the installer all the money I was then disconnected the weekend which was in june when I started calling the dstv call centre to report what happened and was advised that the risk and ***** would call me within 24 hours to assist me , nothing happened I have been making calls every week to follow up and no feedback has been given to me an investigator was assigned sometime in july which he just called me and did nothing there after the owner of ZER and the installer came to my house and was acknowledged that this same installer de*****ed a police colonel and the colonel was present on that day the owner made arrangements with myself and the colonel and advised that they will pay us R500/R500 till all our money has been paid up and took down an avadavat with the arrangement made , the sunday there after I called the owner and no answer I than called the dstv investigator and sent him a watsapp but no feed till now. my services was disconnected by the finance department on 16 Aug 2017 by a lady named Leshano and she advised that she will investigate and let know I called her on 17 Aug 2017 and she said that I must pay R1100 but my services wont be reconnected as the account will still be in arrears but that is not my fault and I did report it in June and never got any assistance I have made numerous calls I have spoke to agents supervisors and now the finance lady who has not helped me why am I being punished for a *****ed installer and had dstv kept to their word of having ***** department call me in June when I logged the complaint this would not have happed and my account would have not been in arrears

I'm very disgusted in the services I received from DSTV as I have never owed them anything up until I logged the complaint and no assistance till now when they just disconnected me without trying to help me and bring this installer to justice and clear my account

I am ****ed and no longer know what to do with DSTV
