Money paid, no service delivery

I tried calling your call centre today. First call went through to contracts dept, gave all security details and was to be transferred to the technical dept. The call was cut. This has happened before. 2nd call I ask to be transferred directly to the technical dept. Cust care says they cant and I have to go via the contracts dept. I am transferred to the contracts dept and then thankfully, the technical dept. I advise that I need assistance as my internet is slow, very slow, everything times out. I am told that the technical dept is aware of it an working on it. I advise the issue has been ongoing for a week. The sam line is repeated. I then ask to be transferred back to the contracts dept. Once transferred, I ask to speak to a supervisor, i am placed on hold, the agent then comes back on the line and explains they are still looking for a manager, the call then goes through to an automated machine asking me to rate the level of service I have just received. So once again, I am cut off and no resolution. I am unhappy with the level of service, right now I would not recommend your company to anyone, I am paying you hard earned money that I can scarcely afford for a service you are unable to deliver. I am not in the habit of giving out free money. Please correct the internet issue or refund me the monies paid for a service which is not being delivered. Thank you.
