Poor service provider with inferior services and systems

Appalling service in all departments. I was due for an upgrade for my data contract on the 1st of July. The consultant who called me on the 30th of June upgraded my contract to a home internet contract. Canceling the contract and requesting for a new upgrade to a different plan was such a mission; 3 weeks later and the data plan contract fee was debited from my account after I had made several calls on different days to cancel all existing contracts and upgrades under my name. I then decided to go for a wifi contract which is also proving to be an uphill battle. I recieved the ****le with the router 3 days ago with an unregistered Sim card which no one seems to know how to fix. I have been talking to customer care agents for almost 2 hours each day to have this sorted out but here I am still data less. Very pathetic systems in place to check processes.
