Leroy Merlin Fourways and Gentech - terrible service!

I have been receiving thee worst service from Leroy Merlin Fourways and Gentech Bought a generator there in May 2022, in August 2022 it stopped working. Took it in on the 7th of August, received no call, no feedback, I had to phone LM Fourways on the 10th, yes someone did phone me then, stating the generator will be sent to Gentech to be looked at. Generator is only fetched a week later! On 17 August, received a call, generator is fixed it can be picked up on the 19th but to be safe, the 22nd of August. I hear nothing, no one calls or sends an update. I call them today 23 August after getting no response on the 22nd. After holding on for 10 minutes, my call is put through to the Customer Relations Manager, the call drops, but she does not phone me back!!!!! Trying to get hold of them, cannot get through, when I get through, again holding on for 11 minutes. The person assisting me does not take my calls now, nor respond to whatsapp messages. Still without my generator that stopped working 3 months in!!! I will never support LM again.
