Makro online big lie

I bought an item online from Makro on the 13th of February and till today. Upom purchase I was told I would receive a my item with seven days. After about 21 days a called their national call center and I was accused of receiving the order which I did not, so I requested them to cancell the order and pay back my money again was promised that someone will call me and month's passed. In April I managed to get someone to listen to me and on the 30th April I received an email stating that the money will be paid in 2-5 days. Today is the 5th May and still no refund. How long should I wait for my refund? Should I wait for follow up team for a whole year?
