Telkom LTE call centre getting no joy.

I have a Telkom LTE device at my house and it was confirmed by a Telkom technician that there is no signal. I was thus in the process of cancelling my Telkom LTE. The technician gave me a reference number to confirm this (***7). This is a week or so ago. <br> Yesterday another technician phone me again once again trying to come again to my house to check the signal again. What for??? It was already checked. I then today called their call centre and told my story to 2 of their employees after 50 minutes on the phone the line just dropped again.<br> Please can you sort this out now? I will definitely never use your service again.
