I am being billed for calls I cant have made?!

1)I took out a landline contract to get ADSL.I was billed for installation despite having a weekender plan.I took this up numerous times with Danru,Mueed and Finlay Peake (all very helpful).Finaly lodged the dispute personally on 23 September the 2nd time I complained.The new bill just arrived and this IS STILL NOT RESOLVED.<br> <br> 2)My landline didnt work but my ADSL did.I also spoke to the above gentlemen about my landline not working. I saw strange activity on my line & told them about it:There is about R7 worth of calls last month that I could not have made (I logged the line had a fault).I have gotten numerous SMSs about the fault & its progress-in short I CANT have made the calls.The gents promised to refund the money-didnt happen.On Oct 1st I was informed the fault was fixed&I made a call to check.Other than this I couldnt use the phone and no one else has access to it as I live alone. <br> <br> I just received a new bill for R55.08 worth of calls+cell calls ALL to numbers I have never heard of(I checked) & when I could not get the phone to even dial! <br> <br> What kind of ***boy company are you running.How the hell are people making these calls from my line.Must be your tech having a grand time
