HUAWEI BAD SERVICE!

On 10th November 2019 i took my tablet into the Melrose Arch Huawei Branch for the screen to be repaired. I was told i would have it back within 48 hours. I then received the quotation and paid the repair costs on the 20th November 2019. Since then i have been in contact with the customer service. I was promised everytime that somebody will call me back and that it is escalated? I then had a call from a Manager called Sipho, who also promised i would have an answer by the end of the day. That was on 27 or 28th November 2019. Yesterday (2 December 2019) when i contacted them again demanding a proper number for a manager who cares about customer service, i again was told that somebody would call me within an hour. Today is the 3rd December 2019, i still do not know where my tablet is or what is happening. Have they lost it? Damaged it more? I need answers. You cannot take the money and not produce the goods!!!!!! I want answers from Huawei NOW!
