*****ing from Customers

Worst customer service ever received. Paid my service as normal. In the middle of the month someone decided to upgrade (without my knowledge or without me even requesting this) my service and then disconnect the service that I paid for. 2 weeks phoning and enquiring everyday and endless so called escalations. And not even one call, sms or email to say that there is someone that will attend to the problem. Today for the first time I recieved a reference nr for for the logged call ***4-Case 2. So my service has been used for 2 weeks and the rest of the month a paid service has been suspended. Is there any ANYONE that can rectify this??? Refund me for the service I did not recieve. Stop making your paying customers victims of 'system errors'.
