Customer neglected and left in the dark

I hate complaining but once again I am forced, by you Samsung, literally forced to resort to complaining and fighting and begging for service. Here’s the situation: I handed my phone in for repairs (broken camera lens) at Tygervalley Shop on 9 February. After not hearing anyting for two weeks I return to the shop on 23 Feb, only to find out they emailed the repair quote to the wrong email address. I accept the mistake and the quote and pay with the promise it will take apporximately a week and I will be phoned to collect the phone. But the week passes with no word. After two weeks passes by I return to the shop on 12 March. The woman who would have phoned me is not there and the gentleman cannot really tell me anything, but assures he will phone me by Friday (16 March). But again the week passes with no word. It is now Monday 19 March, more than 5 weeks after handing in my phone and I am still left in the dark. Just empty promises. I am probably just another annoying client for you to walk over and have at your mercy. Having made three trips to your shop over five weeks, you really have proven to me that I am not worthy your service and you really don’t care. So regardless of how you deal with this complaint, you have lost all future loyalty from me. Your service is appalling and not deserving of my hard-earned money.
