Contract hange

My boyfriend Shaun has changed his contract from 8ta to Mtn. He went to the Glen MTN on Saturday the 12th of Septembef, they assured him this would be sorted out by tuesday the 15th. It is now the Friday18th of Spetember. His line is dead he has been unable to make or recieve calls for the last WEEK.this is completely unacceptable and a disgusting level of service. He called MTN and has been transfered back and foward. He asked the saleslady to check the system for any feedback and she HUNG UP ON HIM. This is compketely unacceptable!!! We are going to cancel the contract today if this is not sorted by close of business today. In addition all our friends,family and facebook will be advised to NEVER use MTN. His number is ***. Sort this out. Please note the I.d number and cell no are mine not my boyfriends. His details should be on your system.
