Help?!!!!!! Lte A is a no go

We received our Lte-A modem & package last week Friday. We have not been able to browse the internet for more than 5 minutes without the internet cutting off completely. We logged a query on Mweb's portal as they advised but after an extremely detailed overview of our problem we received a default response stating that we should try and move the router and other binalities like that. We mentioned that the signal bar is full and we can connect but only for a short period of time. Our ticket was closed and logged as completed.

We aquired this service to save on data cost and have effortless internet but all we have been doing is waiting on the call centre line to get through to someone.

So we are extremely frustrated and disappointed. We are stuck.

A debit order has already been deducted and we have not even been able to utilize this service.

Can we cancel this "service" or will somebody please assist us.
