Poor service

I am so annoyed with Makro. I ordered on line on the 21 April 8 items. I received an email couple of days later that 2 of my items were cancelled with no explanation why. Couple of days after that I received another email at least explaining why they were cancelled. i called Makro several times to find out what was happening and the hold up on my delivery. Every time someone says they will call me back. On the 27th of April I received an invoice for 3 of the items and R50 delivery. On the 2nd of May I received another invoice for the remaining 3 items and another R50 delivery. I called again to find out why am I billed of 2 deliveries whereas I was never given a choice in the matter of splitting my delivery, the lady I spoke with said I shouldn’t have been billed twice she will get someone to call me. No one I did. Again I picked up my phone and called Makro again to enquire about my delivery and the lady I spoke with asked if I received my items as it shows on their system they have been with the courier I said no. I decided to cancel the whole order and she told me it will take about 5-7 days for the refund. I asked if that was the case why have I not received the refund of the other 2 items that were cancelled. She said she will escalate the matter. I thought the point of the online buying is to avoid going to the shops but it seems that’s the only way. The things I bought were not even luxury it was groceries e.g. pasta. I am so disappointed with the service from Makro. Funny how daily they send emails promoting buying online and this happens. I am hoping I will not have to call Makro back to get my whole refund since they already ****** me for billing me for 2 deliveries and I have not even received one item from them.
