Unhappy and frustrated customer

I inquired about their fibre in the beginning of May and it was approved about 3 days later and I received an email as confirmation that the router would be delivered. They had an incorrect address which I have called to correct more than 5 times and was assured that it would be updated. The consultant logged a ticket and provided a reference number and said this would be escalated and dealt with accordingly. Fast forward 3 weeks later, the address is still incorrect and I have not received the router nor the installation has been completed . When I called Ram couriers they advised that they have been sending Vodacom emails to confirm the address which were not responded to because the package has been in storage for the past 3 weeks and today we called multiple times and they still did not have a solution to our problem, instead we are told to call the sales department as our application is still pending due to vetting.

Clear they have failed to fulfill their contractual obligations and have proven their incompetence on numerous occasions and therefore I would like everything cancelled with immediate effect.
