Worst Repair centre service ever

I handed my phone in on the 13th of December, I was told by Huawei customer services that repair could take up to 21 days. It is now the 22nd of January and I still don't have my phone? I have contacted your customer representatives numerous times and I am only met with "the matter has been escalated". I have had no further information, no-one can tell me when my phone will be fixed and when I will have it back. Not once was I informed of the delay in repair, not once was I given any proper information on the matter. I am not sure how Huawei sees this as acceptable customer service, if you give someone a lead time you stick to it, if you can't then you let them know! There has been no contact made, no information given and no feedback! This a appalling customer service and I am truly disgusted. spoke to a very rude manager at the midrand repair center that has my phone and was told no information other than it is being repaired and I will be contacted. Not sure when though? Will I ever get my phone back?
