Bad service delivery

I have been trying to get my wifi service sorted for the last month already. We live in Croydon and since July we have been experiencing a bad connection. We have upgraded to the 10mbps packages and have little to no wifi service. On 31st July I reported the problem to Telkom, reference number: 689CRK310717. I received SMS messages to say that they are working to resolve the problem. But still nobody came out to solve it. I reported the problem again. Reference number: 193CRK210817. I was told that our router was faulty. We have now bought a new router and still can not get our wifi problem sorted. I have been in contact with Telkom today again and they still can not assist over the phone. We are expected to pay our account on time. Yet we don't get the service that we are paying for. Telkom service is ridiculous and I would not recommend it to anyone.
