Melrose Arch Huawei repair turn around time and customer feedback is appalling!

Im beyond upset with Huawei customer service, I took my phone that was working without any issues for screen repair on the 14/03/2021 and was told it will be ready in 2 to 3 days, on the 3rd when i call for eta Im being told that they need to fix the usb charging port which is faulty I ended paying an additional amount for that and told it will take another 3 days. After 3 days I follow up and Im told the part is out of stock and its been ordered they should receive on 24th, I was not pleased with this as I did not have a phone and did not plan for such delays. I went the store to get my phone as is and when we switched it on or charged it nothing happened, so I was left with no choice to leave it there, Manager was not even onsite. Yesterday i made several calls to the store directly and told that the part still has not arrived and it should arrive today. I called again today and they cant even give me an eta, they are saying maybe it will arrive next week. I so regret taking my phone there! They cant even give me a loan phone, this is now going to week 3, im now forced to go shopping for a new phone as i cannot deal with this stress as an expectant mother who is due anytime.
