Pure incompentence by Telkom employees

I app**** for a landline look alike thrgh their call centre in Jan 2015 the wrong items were delivered,because of work schedule,I returned the items to East gate branch 4 days later and was given the following cancellation code:A***4.The sales person who was assisting me at the time said this was going to be done swiftly and she advised me to sign another contract for the landline look alike,to cut the story short ,I signed it because I really needed a landline number for my business.Few months into my contract the torment started,I was billed for the items I returned,they suddenly linked the accounts,so I was now paying for the line that I was renting and for the cancelled items.I went to East gate branch on numerous occasions with no success,I kept paying for this line but the line was constantly suspended because of the amount over due.I recently found out from the Telkom staff member who is \investigating my case\" that,infact,I actually been sharing this line with another person,Mr Naaido.They claim to be investigating my complaint at the same time I am being harassed by their debt collectors and lawyers.After 1 yr & 2 mths,the cancellation is still not processed"
