UNCAPPED ADSL

Good afternoon, in June 2014 my Husband app**** for a Telkom ADSL . He is paying for an uncapped 2 meg line R599.00 per month, and suddenly from the 20th of January 2015 the internet blocked itself out. I contacted their call centre on 10210 and spent a full hour just holding the receiver waiting for an agent to answer the call a gentlemen eventually answered and in return he was so rude and shockingly he announced that we are abusing our UNCAPPED internet we have used 102 gigs so I said to him as far as I know the line is uncapped and its 2 megs and there is no paperwork that states at 100gigs your line will block out and further more he kept shouting 'listen here you abusing the line so we blocked it we have every right to block it when you abusing it you gone over your cap you need to buy top up so I said please sort it out as I understand I am paying for uncapped internet he stated again I cannot do nothing you need to buy top up so I agreed and he transferred my call to the top up sales department and my god an absolutely dumb female answers not knowing what she is doing or what I want so I just hung up. If I am paying for uncapped internet I expect unlimited internet access.
