Poor service

I, Mrs, C.E. de Klerk, have an account at Lewis. I bought a LG Toploader washer at the shop. It had a extended gurantee, as soon as I had problems with the washer I report it, about July. In September, while paying my acc. I ask again about the washer.They replay they will lock a call. In October I complained again. The manager checked my profile and said the gurantee expired 10/10, there was no complains locked!!!! Thy suggested that they send their handyman out, he checked, changed a *****, left, 1 Wash, problem was back, Rupert checked again, said he is ordering a part. Never heard from him again. Doesn't answer [URL Removed] with manager she said she phones him, he will come back. This is more than a month ago! There's no after care at this shop. I told them I have a disabled child, 27Years on nappys that , like the other washing must be done by hand! The person responsible for allof this is Chris. He didnt lock any calls, and thinks he is not to blame, like the rest of the personel!!Please give advice, Chris also have a complain from me on a doublebed,only follow up, nothing happend for the last month, complained more than 6 months ago.He said a amount must be paid, No probl
