Very Bad customer service

it is for more than 20 years that I am a customer of Lewis store Prichard street Johannesburg. I bought a laptop and got a tablet with it the tablet I had problems I took it back to Lewis the sales person (Tshili) was helpful because I told him I want to buy a fridge but I will come back to you I was waiting for 2 full months for the sales person (Tshili) to come back to me I decided to call them and speak to the sales person (Tshili) it was so a long story I will phone you back mam, my boss phoned him he was so rude to my boss and drop the phone in her ear, we phone the store manager Connie, she said she will sort him out and she will phone me back, never phoned me back. I called her after 2 weeks, again she said I will phone you in 15 min still waiting 3 days after I phoned her she said she will come back to me.3 hours after, I got a call from Charlotte to say I must pay R350.00 in so that the repair shop can go ahead to fix it. But I was told that they will give me a replacement tablet and everything was already arranged. I just said ok. PLEASE ANY ONE. SERVICE IS BAD. I WILL NEVER ADVICE SOMEONE TO PURCHASE AT ANY LEWIS STORE IT IS ONLY ABOUT THEIR COMMISION (MAGGIE).
