About a month ago I received one of those calls from a lady from Telkom saying that the copper lines were being replaced and that they will be sending me a new Huawei B525 router. So we received the router and all seemed to be fine and well until we realised there was a problem with the landline that had gone "dead" when plugged into the router. I unplugged the landline from the router and the phone then worked fine again, and the router works fine on it's own. However, the landline is now making an awful buzzing, crackling noise like there is massive interference. I logged a fault, thinking that it must be the cord or line that was faulty. Telkom came back saying that the issue had been resolved. No explanations though, and the phone is still making the horrible noise when unplugged from the router, even when no electrical appliances are in the near vicinity. I have tried plugging it back into the router again - the screen goes blank and there is no dialling tone, just a faint humming noise on the other end. I then thought it must be that the landline handset is incompatible with the new router. When I asked Telkom whether this could be the case, no one, not one person in the sales or technical departments, could offer any kind of advice whatsoever. Is one supposed to use a specific landline phone with the wireless router? If so, Telkom neglected to mention this to me during the initial conversation. I am shocked by the absolute glaring incompetence or perhaps lack of product knowledge I have experienced when dealing with the Telkom staff this past week. I am now going to attempt to go into a store to see if they can help me. If anyone has any advice or inputs, it would be greatly appreciated
