Worst service experience

I ordered products from Ackermans online on the 28th of December 2025,when I tracked on the 1st it showed that it was delivered I went to my selected address only to find that the order isn't there or so they said,I called DPD laser again on the 2nd of Jan 2026 to confirm if they indeed delivered, according to their confirmation they said it was received by a certain person in ackermans stores,I went back again to my selected store which was Tembisa Yarona to enquire about the order,they said they do not have such person (the receiver) at their store and that I should go check at busy corner mall(my petrol) I went to busy corner mall, explained everything and I was told that the supposed to be receipt was on leave the time they say my order was received and is still(on leave) the order was not there,on the 5th I called DPD laser again to re trace my order,I was told to go to Kaalfontein corner again I went there with my petrol that I was trying to save when I ordered on line and had to wait for assistance,(waiting) another thing I was trying to avoid sadly after the lady checked with the courier company as she said they haven't received anything in 2weeks ,my order was still not there,now I'm left with a question mark of where my order is and what's the point of ordering online if one has to go through such.
