Empty promises

I wrote a review on the 12th of Oct about no internet connectivity on Vodacom's fibre network foe 2 days and the fact that since July i have not received my mobile back up router. i first logged a request with them on the 2nd of September for the back up router, the service request was closed and i still did not receive the router. on the 12th of Oct logged another service request and followed up again with Vodacom today and this service request was also closed and still no back up router. i had even requested that i go collect it at Vodaworld or something and they said it had to be delivered. spoke to another agent today and she doesn't know why the 2nd request was closed. The service i have been receiving from Vodacom is just disgusting. i just want to cancel this contract because it is not even 6 months od as yet.
