Explora nightmare

i have been using a PVR for past 2 years , i have never experience any problems until 3 months ago wen i changed to price lock , i saw a great deal when the say R499 for 24 month price lock , i even took the insurance from for R35 a month , i arranged a debit order just to make thing simpler ,first month they deducted R500 second month , they i owe R1800 , i went to customer service in jabulani the consultant said R2100 with no explanation i waited for an hour while consultant is busy trying to locate the billing , by then the debit order did not go through as they where supposed to deduct R535, i then phoned spoke with a consultant who escalated my call by saying i must send my id nu by sms to 37408, no one called me till today , they then stop disconnet my dstv for almost 8 days ,then i went back to service centre , then i was told to pay R798 thats what i owe , without any clear explanation i paid , my dstv was reconnected and it is till on , my big problem is there was no debit order again this month , when i phone multichoice call centre i am told i owe R1600 because i am supposed to pay R499 for price lock and R499 for services which to me is ridicoulously insane , the consultant cannot give me futher explanation about this therefore i request for procedure to terminate the contaract as i believe i was ropped and mis-informed about the price lock , i signed up for R499 deal for a period of 24 month not hide and sick , the least the consultant can do she gave me an excallation number again , sms id number to 37408 ....i dont want this service anymore , i will try other reasonable services
