Worst supplier ever!

I have a acount with teljoy for almost a year now in the begining everthing was great but as time progressed everthing changed. The last to months i did not pay my account up to date because if been struggeling to get my faulty equipment repaired.So i paid a amount of R2000 per month to try and get reaction no reaction received so my first complaint on hello peter help me to get my equipment booked in. So i arranged to pay my acount up to date as soon as equipment is repaired. Three weeks went buy with no cominication. So i phoned in and they said the found the problem and is just waiting for the part so i said i will bring my acount up to date the next day.<br> Next morning at 9 am i received a call from their tecnical department saying sound system under warenty and lg must replace it so another three weeks past and no replacement yet. Today i received a letter saying my acount is in arrears and im getting billed for equipment i dont have and my contract staits if faulty get repaired or replaced now the customer gets billed for a unit that is faulty from supplier. The worst part is teljoy listed me on itc for not paying my account up to date but the do not keep theire terms.
