Shocking service from everyone at Builders Warehouse!

I saw a special on your website - went to Strubens Vally and was told they can’t give me the special as it’s only an online special (although your website does not say it was for online purchases only, well, not that I could see!). My order was processed on Wednesday. Thursday I get a call to say I haven’t paid, I explain that I have, and I get told, no problem it’s a system error and it will be sorted. Another phone call and I’m told the money has been received and delivery will take place on Thursday. I call to find out where the delivery is after 5. I get a call back to say there’s a problem with the system (again!) and they couldn’t print the delivery note so delivery will take place today, Friday. In fact, I was promised. After 20 phone calls (yes, I counted them) in 2 days, speaking to 5 different people, I still have NOT received anything - not even a follow up call from 2 hours ago, or even from the lady who was “on tea” when I accidentally put the phone down on her and tried to call back. Since I cannot phone through to the store directly, I keep dealing with people who “will pass on the message “ or “call me right back”. In fact, person no 5 was quite rude to me about it all! I won’t name names here, for now, but I have all 5 people’s names. You tell me my money is at head office - THIS IS NOT MY PROBLEM! I have paid! It’s YOUR issue, not mine! Yet here I sit, without so much as a courtesy call to say it won’t happen today. Disappointed and disgusted in your service from all 5 people, or complete lack of! Oh wait, make that 7 if you count the 2 people that sent me away from the store and told me I had to buy and pay online - and now I get BS excuses for non-delivery, when I ordered and paid as instructed by your store manager.
