Bad internet connection amd passing the buck but n

Mweb is my service provider for my internet , and they handle my adsl line , i have been complaining for the past 10 months about their connection being intermittent and very slow and also no connection at times, they always say its telkom and they log a call with telkom , telkom has been very acvomodationg , they have been calling , following up and repairing my line even if their system tests my line as being perfect , i have changed my router many times trying to solve the problem by myself but i stil find it hasnt solved my problem , on wednesday telkom called again saing they can not find a fault and that mweb must have a look at the ISP , and they have done everything again and conform that mweb must sort out their service. When i ask to cancel my services they freely accept it and even guide me how to vancel my service online. Mweb you are a disgrace when it comes to keeping a customer in todays competitive market . Check ur revords for the past 12 months you have followed up twice only with a call , i have made over 20 calls to complain . Telkom has always called back after you log a call to say they must investigate the line, why are you then my service privider.
