Huawei Menlyn - Stay away. No service

I tried to book in my P8 lite phone at Huawei Menlyn on 10 December 2019 to replace the battery. They had a deal for R199 to supply the battery and labour. I was send from one person to the next to book the phone in. After 45 minute I stand up and demand to be helped straight away. I left the store without a piece of paper to acknowledge the transaction. I only receive a SMS for proof of payment that was followed by an email with the same information. No reference number phone number or contact person. The spares will be in the store by 12 December and the phone should be ready on the 13th. If I replace the screen and the battery, they have the spares and can do the work immediately. My screen is still fine. By 24 December I did not hear anything and travel to the shop just to hear that they are still waiting for spares. This time a got a phone number and a name to contact, but they will keep me up to date. During the following days the phone number goes either to voicemail or no answer at all. On 2 January 2020 they call me that they have to replace the motherboard that is faulty. I request the conversation on email to which I respond straight away to go ahead. Further no feedback. On 16 January 2020 they let me know that the phone is ready for collection. I payed by card and again left the shop without even a slip. This is not bad service, it is no service at all. No communication at all. No means of communication at all. Stay away from Huawei.
