Horrible Service

In Dec 2017 I bought a twintub & tv at Lewis on account. Since then the tv has been for repairs 3 times, now currently this year will be the 4th time. When switching on the tv, the light is green but no picture & no sound. I called the nearest Lewis branch the line is forever busy. When my call is being answered I get put through to various people, then eventually the branch Manager. She picks up the phone but she does not talk but I can hear people in the background talking after waiting for her to speak she puts the phone down in my ear. I then called the head office I only get a reference number. They do come collect the tv after a few weeks of calling back & forth. Yet every month they deduct their installment. Even if I do have the tv or not. They don't even send a loan tv, while mine is in for repairs. When the same tv returns after a few months the tv works but something is always not working properly like it did before. I try to accommodate & understand but the service I received so far is poor. My biggest regret is open this freaking Lewis Account.
