No one in Huawei knows where my device is

Good Day

I took in my Huawei 7" Media Pad Youth for software repairs on 15th December 2017 to the Huawei Repair Centre at Canal Walk in Century City. The lady that handled this was Charmaine (pregnant and with dreadlocks) and she assured me that my tablet will be ready within 2 - 3 working days because "it's something small" in her words, I then paid the R150 for the technicians to have a look at it, she said the additional amount after repairs would be R260 . I then phoned the following week on Wednesday 21st December 2017 but she wasn't there and strangely enough nobody could follow up for me as she's the only person that deals with the repairs. I then went to the repair centre in Canal Walk on the 22nd December , Charmaine was there. She took my check in document and went to the back and my device was not ready. After having ASSURED me the previous week that it'll be ready, she then told me a long story about how there are over 90 devices in for repairs and I reminded her of what she'd said to me that mine was just "something small" and she suddenly remembered, her tone changed and she said that it'll be done within 2 days and that she'll DEFINITELY call me the next week. I haven't received a single phone call with any progress update, I keep calling and nobody knows where Charmaine is nor where my device is. When will I get a response? Can I just get the R150 back and the unrepaired deice so I can take it elsewhere? How long is 2 - 3 working days?
