Unable to finalise a purchase on line

I ordered a terrace lounge suite on promotion on Makro on line 8 September. When I checked out and payment was due, the delivery cost changed from R 55-00 to R 210-00 from the one page to the next. I logged a query which subsequently has been dealt with by Pricilla Mogogole. She asked for the product number which i sent and after days of back and forth it was confirmed I can stil get the set a promotion price - it was NEVER the issue - i queried the discrepancy in the delivery cost.<br> It was confirmed the cost is R210 and not R55 but never got an explanation about the difference.<br> I asked to get a final invoice on the promotion price with delivery, and am still waiting.<br> It is just so frustrating to have the option to purchase on line and it then takes 2 weeks to do the deal!?<br> Is it really necessary? I wanted this to be delivered ASAP, but now the tenants are away and cannot accept delivery until 28 September.
