Pathetic service from huawei cornobia branch durban

gave in my phone, HUAWEI MATE 10 PRO in for a battery replacement on the 16th of July at your cornubia branch. The consultant informed me it should take no longer than a week to repair the device, but when ready they would call or message me. On the 18th July Saturday, I received a message informing me that my device was ready for collection. I went into the store on Monday afternoon to collect, but was informed that the device is not ready has the battery arrived in the morning and would be ready by Tuesday. I had not received any feedback since then! Today the 23rd I go to find out what is going on, the manager who is so *********** and such I **** and lies on your face! Had said the phone isn't ready because the battery did not arrive! 1. How could I receive a message saying that my phone is ready for collection? 2. How could the consultant say that the battery arrived on Monday and the device would be ready Tuesday? 3. How long does it take to order and replace a battery? 4.how can a manager lie and say the phone is not ready because the battery is not here, yet I have an sms stating phone is ready and the consultant said the battery arrived Monday? 5.where is my phone and what is going on? I called your customer care line immediately and spoke to a consultant, I explained to him the situation and asked for the area managers number he said he would escalate and email me, and he will sms me the area managers number, but he sent me the number of the same manager of the cornubia branch and has not emailed me yet. Please could I have a contact number for you head office in durban and a management number at head office level. Your cornubia branch staff really have a don't care attitude and it shows in the amount of angry dissatisfied customers. I will be posting this on social media to see how many other people have been going through this pathetic service from your branch and I will be taking action should you not take your customers complaints seriously. Please hire mature consultants and not immature consultants.
