Manager coming to my place every night for money

I'm am very disgusted and actually supriced on how lewis handle their customers. I bought a sound system last year august..October it stoped functioning and they failed to repair or replacement but yet every month I paid accordingly and payed for insurance. The manager is soo rude to an extend he tells me I can't decide on what I want o buy that's why he didn't want to help me in the first place...first thing the product I wanted he said was out of stock and he is the one who said I must take sinotec hence tele***en is out of stock..then a month later his sinotec stoped functioning. I went to the store million times to enquire on my repairs or replacement but the manager himself kept hiding from me..I don't think I'll ever buy from lewis stores mabopane ever again.I'm sick and tired of mandla Hlatswayo the manager and his driver sam. Because the last time I was there hw sweard at me telling me to fotsek he is closed. And it was 15 minutes before the store closes. Now I wrote to hello peter in February that's when they re invoiced me.... Now what disgust me now the manager comes to my home after 8 o clock at night telling me he want te payment on on hand if I don't have money I must go with him! So what I'm trying to understand is that where is he taking me and why should I pay out of the shop. I can't take it anymore people coming to my house telling me they need to take me with....I want to understand where was mandla wanting to take me? 8 o cloclear night harassing me. I'm tired of his threats and harassments May lewis kindly explain to me where does mandla want to take me too because this is a serious harassment for a female young lady like me. I don't want your products and services anymore. So may you refund me and take your goodies. I'm tired! Make it a way that lewis and I no longer do bussiness together. Just find a way how. Tired of the unprofessional manager coming after me all the time but failing to provide me with good service..insulting and Harrasing me...MANDLA HLATSWAYO MABOPANE MANAGER!
