Migrating a data contract

Don't know if anyone else has had similar lack of action response from Telkom Mobile. Migrated LTE 10+10 to LTE 20+20 about 3 weeks ago. Now cannot find out when this will actually take place. Was told by call centre that order is on queue to be actioned but nothing has transpired for two weeks. Would like to give them more money but Telkom Mobile not interested or they don't need it or they don't care. Call centre agents and Telkom shops have tried to assist but it seems the back office is not responding even to their own people. Really pathetic service
