MTN have really dropped the ball since implementing a new system

I have been a customer with MTN for almost 20 years. My contract is on my personal name and debit order goes off my business account. Did my every 2 year upgrade a few months ago, due to the new system they implemented, the debit order must go off the my personal account now. Each time I go to a store to set this up, they say it can't be processed and must come back at the beginning of the month. Then I manage to set it up but went to a store yesterday to be told that the debit order is still not setup, despite the last person i spoke to confirming it was setup. Looks like the new system they implemented has taken them back in time instead of moving forward. In the times we live in now, it really should not be this difficult to setup a debit order. Besides the debit oder, there has been endless issues with them since doing my upgrade.
