Service Complaint

I have had a terrible experience with Mondo and Telkom. Two years ago I received a sales call from one of the Mondo consultants for a router and it was delivered by DSV. The router did not work, I have never used it - I went to the Jabulani mall Telkom branch to possibly get it fixed and I was told to call Mondo which I did. The agent I spoke to asked me to press a button on the device and I followed instruction but it never worked and if you guys could also check your records - no data was consumed or used on that specific router. I have been sent statements by Telkom advising that I owe them. I went to Telkom and asked them to cancel this router and advised that I would not pay for a faulty device that no one was willing to replace or fix and why was I being charged all the while when I was not using the router? I am highly disappointed with the service received from both Mondo and Telkom. I will not pay for something I did not use. I spoke to Silindile from Mondo who was of no help and did not even try to resolve my complaint - we spoke through their Live Chat system online and she asked me to provide a number which I contacted their company from three years ago, firstly they have records of who and on which number did they contact the client on - I know this because I work in the same industry. She then sent me a final message asking me to respond to the "which number did I call them with..." and two minutes later she ended the chat because I did not answer in that two minutes. I am truly exhausted by these two companies. Please be aware of Mondo sales calls because their aim is to get a sale out of you and you will never hear from them or get any assistance and the blame will be placed on you. The service is dismal!
