Makro stonewalling online purchase enquiry

I ordered and paid for garden equipment which, Makro say, should be available for collection at their Ottery store within around 5 days. When I phoned their call centre (five days are up), I was simply told what I can see on line, namely "order in progress". When I asked to be put through to the Ottery store, the consultant said she would need "authorisation from my supervisor". This the supervisor presumably refused to give; I was told "someone will call you". Makro have my money, but have stonewalled me, and I am not happy.
