Not good customer service and bad products

I do have an account with them. And my payment isn't in arrears or anything. But already from the 25th they start calling me not stop to ask when will they receive payment. My payment is only like R676 which I am suppose to pay by the 30th. And which I will pay at the 30th like I am suppose to do. It is very uncomfortable if they keep phoning while I am busy working with my residents. Or if I am busy with meeting. And it is also another thing products they sell isn't so good as they made it. I did bought two electronic things with them and I will definitely not recommended anybody to buy electronic things there because the working condition of it is not good at all. I don't know if I have any warranty on this things but I don't even want to ask them to come and replace it because then most probably while they take it to maybe fix it I will have then nothing to use but they will still ask payment and chances very good that they will phoning again not stop to ask for payments. So to round off my story I wish I know before hand how Homechoice treat customers then I would never ever even open an account with them. I think it will take me about 10 months to year then account will be clean because the amount I own in total is just over the R6000 and my amount I am paying monthly is R676 but if that is finish I am also finish with Homechoice. I don't want to experience this thing off again you been phone like daily when account must first be paid by the 30/31th of the month. That is ridiculous. And very annoying.
