Telephone line suspended

After everything that already happened i got a reply for telkom after 2 complaint that stated they will credit us for the installation amount they said we need to pay +-1000 that month and +-550 the next. We proceeded the payment of 1000. Then after not getting a statement for 2 months they decide to cut or line sent us a sms the next day told us we need to pay 954.28 to be reconnected. We paid another 1000 and its day 3 after payment and our line is still suspended!!!! What must i do to get service out of telkom??? We tried phoning yesterday waited 20min phoning for our cellphone with no one picking up and dropped the line..... So very very dissapointed thinling about canceling every fed up!!!!!
