NEVER HAD A MORE PATHETIC SERVICE IN MY LIFE

this is my second time complaining about MTN , i had a contract for 24 months and the rate or installments were R 1869.00- R 169.00, i have always paid R 200.00 and more when i had, in June MTN was striking so i did a payment to absa and asked them at that point to connect the line and cancel the contract in august. in July i made two payments and forwarded to customer care and asked for a statement reflecting a zero balance,they responded in august after i contacted them cause my line disconnected stating that i need a 30 day notice period,i responded with the emails dated June requesting cancellation, thereafter i was told that the contract had not been cancelled and needed to pay for august and September and amount of R350.00, they sent me a recon that had no explanation or sense just two extra amounts adding to R350.i paid R350 even thou i did not owe and stated that as soon as the issue is resolved they need to refund me however i made payment just so the line would be connected. its been 6 days since the payment, there is no response and my line is still de-activated. i have had to get another sim for the interim as i cant make nor receive any calls
