Bad service

I cancelled my line a month ago and requested the line be disconnected on a certain date. This was done perfectly however my new service provider is trying to connect my line and advised the libe has not been released. On phoning supersonic they advised I still have an outstanding bill. I then advised I made the payment 4 days prior and why was I not advised this is the procedure. Houston we have serious problems with service delivery in South Africa. I subsequently sent an e-mail with a proof of payment and was advised that the consultant does not know how long it will take. "Rish I have to go to cancellations". What an inconvenience am I causing is my only thought. No respect that we work from home to earn an income.
