Unsatisfactory service from Mweb Business

I signed up for an LTE sim and router with mweb beginning of April. when it was delivered there was no sim card.I logged a query and eventually sim was delivered on the 12 but than there was no issue the sim was not activated, logged another query which was resolved on the 19. I had credit issues with them where I was getting billed for days I had not even received the sim and service was inactive. I queried the credit and eventually was helped but I was so tired of the constant back and forth I decided to cancel the service by end of April. The sim was month to month but the router was on contract so I had to settle it. I paid the full amount for the sim and service was cancelled end of April. But the data that was on the sim I didnt get to use because they deactivated the sim. I didnt complain about that thought its fine I got the router but been testing the router all of May thinking maybe my area had no coverage but the router has since had no internet access since I cancelled the contract with Mweb, so basically I paid for a router that does not work. I am very disappointed with the kind of service I received from Mweb. I wanted this router fixed because I paid for it.
