Dishonoured Paid up letter request to date

I've since requested a cancellation in August & was told that I was liable for the last debit order before they could even consider a cancellation. I therefore had no choice & yet again made payment thereof. Since I was told I would be receiving the paid up letter thereafter I waited. Upon seeing no response, started following up & was ONLY THEN told it will have to be requested from another department & will take 72 hours, only then will it be forwarded to my email. After the 72 hours, followed up again. Was told the request was done incorrectly. A new one was done, given a new case number again. I've been checking my emails ever since then, nothing. If there was a zero rating, I would definately give it to them. Any hopes of ever receiving my paid up letter are zero looking at all the hassles I had to & still going through with Telkom. I also logged a fault whereby I purchased a data voucher that didn't provide the data on my router once activated. Went through about three consultants before I could get sensible response as to what the problem was. Was told my data reflecting on their system but the telkom towers were off in my area, a fault would be logged & a technician would contact me. I was never contacted & there was nothing they could do regarding my voucher that ended up expiring without having access to the data. Was told no reimbur*****t would be possible. I will definately never in this lifetime recommend telkom to anybody who wants to remain sane cos you end up going insane. That's how I'm feeling right now each time I even see their advert anywhere.
