Absolutely Terrible Service and No Communication

1 month back, my contract expired which I was paying R300 p/m including a Samsung phone.<br> Next bill I get it has tippled in price cause its now out of contract. I contacted Telkom and they credited me for the data which was charged. Shortly after I have send 2 requests via email to be downgraded to Prepaid (which i have proof) and i haven't heard from anybody. Tried calling the cancellations department but you cannot call them as you can only email them. I've tried speaking to various agents but they are completely clueless. <br> Today I get an SMS stating payment has not been made and line will be cut if the account of R1000+ is not paid immediately. I want my Cell number downgraded to prepaid immediately and reimbursed the monies you have taken.
