horrible service from makro

I placed an online order for a Smartphone on the 25th November and paid in full for 2-5 day delivery selecting the Silver Lakes branch.the site showed stock available at silver lakes,by wednesday i had received no calls or emails,when i called they said that they don't have stock and will receive by friday,to date i have received no calls or emails and still haven't received my R4069.99 smartphone.Silver lakes online department have not called and do not take my calls,I've requested a refund online and via email as telephone calls are ignored,my emails have also been ignored.I am at work from 6am until 7pm so don't have time to go to a branch and get my refund from them.Absolutely shocking service from what is supposed to be an international company.
