Disgusting Service

I had taken up a summer contract on 9 January 2015.@the city view branch.the billing department said they forgot to debit my account.I contacted them in june telling them upon checking my bank statements that they were not billing me then contacted the branch on several occasions , but nothing was done to correct the problem. i contacted the billing department .I was then given Shaun Smith' s details..my services were disconnected on 15 may 2015.the services is still not reconnected. i asked to cancel the contract but I was asked to pay penalties for an error that they have made.Totally disgusting service. To date I have not been given any feedback I want this contract cancelled without any penalties charged.
