Worst Technical Service I have ever had!

Last month on 8/05/2019 I sent my LG G6 in for repair, the sales person said the repair would take 2 weeks and they would let me know if the phone was repaired or there would be any additional cost that must be paid. I went back on 23/05/2019 and they told me that the battery was the problem and I needed to pay for it to be fixed when I asked them why they did not call to tell me they just through the blame to someone who wasn't there at the time. I then told them they should fix it and they told me that it would take a week and the phone would be there. I went back on 2/06/2019 and they told me the phone was still not there but it will be there by the following week. I went back this past Sunday 09/06/2019 and its still not there and they said they that it was supposed to come today and they would call to update me. I have been without a phone for more than a month now, your quick to deduct money from my account but when it comes to your after sales you are pathetic. This has gone on for too long now I want to know the status of my before end business day tomorrow
