Huwaei battery replacement offer a ****

After seeing the battery replacement offer for R199. https://consumer.huawei.com/za/support/battery-service/ I drove all the way to Tygervalley Huwaei service shop an hour an a half drive from my house, to be told that firstly they don't have the battery (P10) and then If Icould leave it with them for 2 weeks so they book it in and order the battery. There is no way I could leave my phone for 1 day let alone 2 weeks. I called the customer service twice and was told that they would look into it and get back to me. This never happened. Why advertise an offer that cant be upholded. This is absolutely disgraceful and bad service and I certainly wont ever buy anything from Huwaei again. No respect or care for their customers,
