Openweb poor customer service

I app**** to upgrade my internet service to a better and cost effective promotion on my current adsl line and modem. A duplicate account was created . I imediately requested for a correction of this situation so l can keep only one account as l can't run 2 accounts on one modem. It took more than 1 and half months for open web to address the issue. Meanwhile, OpenWeb decided to bill me for the duplicate account. I decided to cancell both accounts due to poor handling of the case. I moved to a new service provider after completing the 1 month notice period. Two months later, OpenWeb came back to claim for payment on a 1 month notice on the duplicate account which I couldn't use simultaneously. I agreed to pay them R427 by end of May. Today they came back with a higher figure of R506.23. I have no problem paying them this, but I just want to express my displaisure at the luck of courtesy and consideration that OpenWeb has towards their customers. I did not want to leave openweb, l just wanted a cost effective and efficient service for my needs. But OpenWeb, seems to value money as little as R209, over keeping a customer for life. I was planning to go back to Openweb from May, BUT, the way they treat customers, is very unprofessional. You get different people replying to your complaint, going round in circles.
