Awaiting repairs. Bad service

MTN Kolonnade. Where do I start? The 29th of October 2017 I brought my LG G5 in for repairs. Services was absolutely shocking. Poor! It's been 5 weeks and I am still waiting for my phone to come back from repairs. I have been phoning you daily. Everyday you have a different excuse. Then I get told that my phone was only taken in to repair on the 17th of November. So you kept my phone at your store for almost 3 weeks before you decided to send my phone in after telling me my phone just has software updates that needed to be done the for it will tale 14 working days before I get my phone. In those 14 days you had not even sent my phone in. Now you tell me you are awaiting the parts to repair the phone as the phone freezes, my phone was not even sent in for that problem as I didn't have that problem. You deduct money from my account for a devices I have not even had for a month. You quick to take people's money but you cannot even deliver proper customer services! I expect to receive my phone or a new phone TOMORROW!!!!!!!!! 4 December or I will stop your debit order and you can keep my phone! Clock is ticking.
