TELKOM SLOW SPEED

My husband and I have ADSL with Telkom and for the past couple of months it has been quite slow. We heard about the break in the sea and left it because there was a bigger issue than Telkom but it is still so slow and we have been trying to contact the call center for the past 2 weeks now but have either came across unprofessional staff who put the phone down in our ears or do not know how to speak over the phone. We tried to log a fault and our fault was closed for insufficient details??? Why can't someone just give us a call to fix the issue. It is no use we are paying for the service and have never missed a payment but not receiving slightly close to what we should be getting. Please don't get me started with your Telkom app as that does not work at all on our side. Can someone give us a call URGENTLY PLEASE.
