Poor service delivery.

Transferred from pillar to post. Received a call during June to increase my airtime at a small additional fee. Agreed to this. Apparently with this, my contract has now been extended for a further 2 years. Who does this without the option of a new phone ? Query eventually logged, however, could take 14 days to complete. I was advised that I am a client with an exceptional rating, but the service I am currently receiving is not acceptable. Furthemore, received a laptop with sim on new contract, at end of May. Sim still not activated. This is also not been sorted.
