building maintenance

i have been staying at one of afhco buildings in Johannesburg for the past year. HAYANI at end street. when we 1st moved in we had problems with the same issue but they quickly sorted and fixed their installations however, as of september last year we started experiencing problems with the dstv connections were you would go for days and sometimes weeks without watching any dstv because of installation problems, my problem is till date the issue persists and yet nothing is being done about it you can watch 4 channels out of a full dstv bouquet where you pay R789 per month and yet they want rent in full month in month out, no compensation no explanations. i have sent dozens of emails that are not honored , when you call the caretaker he doesnt pick calls or will tell you we all experiencing the same problem but thats just it why cant they not get people to fix the issue of installation, im sorry but i cannot be paying so much and yet not get the pleassures of my money because of afhcos own mistakes on not hiring the right personnel for the issue, we have been patient but nothing is been done yet when you wish to move out they tell you how you will not be getting your deposit back forgetting its of an inconvenience from their side that you considering moving.
