No coverage of lte and contract no canceled.

I have ordered a lte router on the uncapped package. I ordered it via the call center. The operate checked and confirmed I have coverage in my area. On receiving the modem does not work. Called them and told me there is no coverage and the modem is to returned. Someone will call me to arrange pick up. Call in again then canceled on line. Uploaded my ID and no reference number was given. Was told to use the person's name and time I called in as the refence. Three weeks later still getting billed. Called in the is morning spoke to Nkanyiso Mazibuko. Told him the entire story. What a waste of my time. Tells me he can see I called on the 3rd and can see I requested to cancel after 17days. Then tells me I need to call 081023 because he can't help. Total waste of my airtime. Can someone from Telkom please assist.... I'm at my wits end with Telkom.
