Price lock/ Customer number ***8

I've got a problem with my Dstv account and it has got to a point where im feeling depressed about the whole situation, regretting why I bothered with price lock. I have been calling Dstv the whole of last week, and it seems it will be the same again this week because I keep getting disconnected because of non payment. Your consultants keep promising to call me back or to forward my query to the Price lock department who are the ones who are suppose to call me but till now, I have not received one phone call from either. I don't know what to say, or to do anymore as my grief falls on deaf ears, If it were up to me I would cancel my subscription with Dstv permanently but my son wants to watch cartoons. I know I was behind with my installments, I made arrangements to pay R1000.00 so that I can be back to the normal installments, then in November 2017 I went to Dstv Maponya Mall to find out how far along am 'I , how much was still outstanding of which they said I was behind by R150.00 which I said I will pay in December. Then to my surprise, now in January, I received an sms from Dstv that I owe R1900.00 that's when I started calling cause I wanted to find out how I got to that amount. The first consultant I spoke to, Tshireletso explained everything to me and said I don't owe that much, I still owe about R150.00, so she will complete a journal which she will submit to the team leader for reversal then I must check on my self service after 24hrs to see if everything was fine, that was on the 11 January 2018. When I checked after 24 hrs nothing has changed, I called again on the 17, spoke to Rodwill who didn't' assist ,he just said he will send a request to Tshireletsho to call me. Called again on the 24, spoke to Lethu, who was trying to assist , and me being frustrated, I was shouting cause it seems like people do not hear me when I talk, she said she will send a request to pricelock department to contact me, I have not received that call as yet, called again on the 25, spoke to Macdeline who was very rude and didn't give me a chance to talk as she kept telling me I should pay my bill, she told me I owe R1200, I need to understand how I owe that much when I keep paying extra every month. Called again on the 26, I don't remember who I spoke to as I was on the road, she promised to look into my account and get back to me on the 27, she never called back. Again, yesterday afternoon (29)my son calls me to tell me that we have been disconnected yet again, I called and spoke to Asanda who kept telling me that she has a system problem of which I advised that I did not have enough airtime and my call will be terminated, I did confirm my numbers for her to call me back but she didn't. Can someone please advise me on what is going on with my account, why do I owe R1200 when I was advised twice already that I owe less than R300.00. I've ran out of airtime and I know I wont get compensated for that cause "I don't pay my bills" that's why I keep getting disconnected, even though I don't understand why my bill does not decrease. Will someone call me now or do I need to come to your Randburg offices now?
