I've bought 6 phones at Makro Online,payment was successful and I received and confirmation sms that my order is successful they are busy with my order...the next day I received an Email and Sms that my order is canceled due to price error and I'm gonna be refund within 2/5days

I've received an R50 refund..they didn't refund me all my money I've been calling them everyday they are busy lying to me saying I will get my money it's been a week now calling them and they keep saying I will receive my money before the end of the business
