Breach of contract data no. ***

So, I upgraded my data contract, as the old one expired. New contract is a Made For Home 30GB (50GB anytime and 60GB night express)with B612 device. cost R 669. I get 30GB pro rata to the 14th Sept. Then 30 day and 30 night. I go into the store and complain. Debit order date arrives pay R 969. go to store and complain again and again. Get sms from MTN, recharge date now on the 9th of every month. NOT! Also on the 9th sms "Your MTN Made For Home Office 20GB bundle has been activated???? Recharge date 12th Oct. get 30 day and 30 night. go to store and complain again and again. Get 40GB night on +_ 14th Oct. Go to store and complain again. "It has been escalated " they keep saying. ENOUGH IS ENOUGH! Awaiting your speedy response.
