Very poor service experience with Leroy Merlin

Terrible order fulfilment & a nightmare to deal with trying to get resolution . Order value circa R3000 . Order placed 5th November used Pay Flex to pay for goods. No order confirmation received from LM no goods delivered. Phoned LM on 20th Nov - without order # could not help me & could not locate my profile with e mail address I provided ( was not interested in my dilemma) . Made contact with Payflex as this was the only record of sale I had - PF has been liaising on my behalf who in turn has repeatedly followed up with LM. There has been no proper comms to me - I get visibility of ticket status from PF which must be the process the 2 companies use to communicate with one another on order fulfilment issues . After several follow ups by myself to PF & then PF to LM my ticket status was updated to refund 2 weeks ago -but no refund provided and just as frustrating no communication re confirmation of process for refund - no customer comms at all no apology etc will not buy another things from this company !!!
