Mcdelivery, call centre and employees are just as

On the 23/12/2015, I walked into McDonald's Lyndhurst to buy food and used cars, transaction went through on my side but the insisted it didn't on theirs, so I paid twice then was advised to wait for a maximum of 12 hours till my money is reimbursed. To date no money. I phoned call centre and spoke to the useless Nomsa Mhlongo, whom I phoned again, I could hear them laughing but not taking calls. Then phoned Lyndhurst manager who told me that his boss says I should provide my private bank statement all these at my ost. I refused, and they could not help. I ordered food from mcdelivery service twice in three days, they could not or can't deliver. I'm not loving it
