Debit Order DOUBLED during LOCKDOWN

My debit order deduction has been doubled without warning! I am *****ed now as I have other bills to pay and MTN has decided to charge my bank account double my usual monthly subscription. Disgusting move during the Lockdown as the 135 number doesn't even have the option to put you through to an agent. Good job *****ing me over this month MTN. I need my money back now!
