Telkom Disaster & they Handed me over for what???

in December 2016 we moved out of address in Muizenberg and advised Telkom we were leaving and we also resubmitted in Jan as Telkom has this cheeky clause that when you send an email re cancellation they have " 30 days to respond". at end of April 2016 we received bill from Telkom from December - April for THIS line that was cancelled. WHAT???? it has taken us until middle of June but finally the amounts we credited BUT ONLY after much back and forwards and motive actions and emails and showing proof that we had submitted. in the final analysis there was an amount of R514 that seemed was due ( no idea how), but we agreed to pay this. We actually did pay this last week on the 28th of August. but since then i have been bombarded by the most vile collections agency persons. the people call at all times of day and night and on weekends too. they are looking for the R514 that was due, that Telkom had the temerity to hand over? the 5 months incorrect billing was never my fault. we proved this. I have just got off the phone with yet another of their collection agency stooges. uneducated , ill equipped and zero chance of getting ice from an eskimo with hostile attitudes and rude conversations, ****bags. i would like Telkom to tell this MCD or MDC to go away and get off my case, i would also like to know how Telkom will apologise to me? over the last year we have had so many issues on other ads line that we rent and we are often without service and we are still billed and we still have to pay. I feel that Telkom needs to look at its employees and its subcontractors and hire in new fresh more pleasant and educated people in all departments. I think Telkom is a joke and i will be doing what i can to make sure that i can find suitable alternative . total con artists considering i have paid over R200 000 in phone/adsl bills in the last 10 years between personal and business, you would expect some level of professionalism when dealing with accounts/billings and cancellations departments. what a total joke.
