Worst service provider and customer service

I have 2 contracts with MTN and after upgrade of the one contract the agent cancelled the 2nd contract out of error. Countless calls, countless visits to the branch and 3 months later not resolved. In the interim they have billed and deducted R8000 for the cancelled contract and NOT reimbursing or resolving the issue with the cancelled contract. Absolutely no one in service is interested and empty promise after empty promise! NO ONE ever gets back to you. I WANT MY MONEY BACK! Never a manager available and escalating does not help. Im appauled by the level of service, disgusting to say the least. Quick to debit but when it comes to pay back they distance themselves. I would not recommend this company to ANYONE. Been a client for 15 years!
