Poor service

IL have bought from Makro without a problem but now I have experienced an issue. Bough a set of chairs and table on 24 March. On the 29th I received a mail saying it was ready for collection.. On 6 April I phoned to find out where it was only to have a service call centre person say that she could not help. Later that day the courier arrive with a box. I asked where the other box was and he said that there was only 1 box. Contacted Makro and was told by Call centre that there was only one box. Have now been in touch with the supplier who said that Dawn Wing Couriers collected 2 boxes on 29th March. I contacted Dawn Wing and they said that they only collected 1 box. Still trying to resolve. I believe that Makro should have been sorting this out as that is who I purchased from. I have sent a couple of emails to them without any response.
