Worst service ever at Huawei Melrose

Not impressed with the quality of my P30 Lite and the service I received at the Melrose Huawei branch. I upgraded my handset from a Nokia to Huawei on 29 November, as of yesterday my camera is faulty. I went to the Melrose branch to find out if they could do a software reload as I suspect this would rectify the fault. I am not currently working in the cellular industry but have had 14 years experience working with handsets, hence my request. Standard answer from the lady helping me was, book it in, 3 to 5 working days, in this instance it would mean I'd only get it next year which is an unacceptable amount of time to wait. Having been in a customer facing management role within the cellular industry it is my experience that I would make a special effort over a holiday period and especially if the handset was just on a month old. I requested to speak to a manager to see if I could get anything other than the standard book it in reply. My request was not even acknowledged, I asked 3 times each time I was blatantly ignored, not even "he's out" or "he's busy" she just proceeded to ask me questions regarding booking my handset it.
