UNACCEPTABLE TREATMENT

I have been a business account holder for more than 10 years and have always run a debit order, this month for some reason MTN decided to not run the debit order and I am still trying to find out why. After receiving email communication that they will debit at month end, my services have been suspended. I cannot get hold of anyone at MTN I just get put on hold I run my business from my phone and I have a very sick mother who may need me at any point I find this completely unacceptable and I need my service re instated immediately You can be sure I will be taking my business elsewhere once this is resolved and I will be sure to post on all social media about this disgusting treatment.
