Complain

I have had a telkom wi fi for about 2years now,in the past 7months i have through a lot of problems,especially through network if you are lucky there is very little or no network,it the past 3moths the thing is not even working i tried to put notice of cancellation and i was told to go on line and i go online its says i don't have an account. I went to Alberton telkom and i found a telkom employee who could not assist me who told me to do it online but i can't. Now i feel its a way of getting my money from me .Now i can't cancel the account. I don't know what to do now i must keep paying for something which is not working and i don't need it anymore.
