Rude manager junaid ********* management!

The service at makro amanzimtoti is unaccetable. I brought a laptop from them which had a hardware fault two days after purchase. I took it to matrix who said that they refused to look at it as there was a hardware fault and i should return immediately. I returned the laptop on a thursday and asked they please speed the process up as i re**** on this for work purposes. The manager assured me it would be made priority and would be done the following day. I had no further feedback. The following friday i returned to makro to recieve feedback and was told that it had only been couriered that day to be looked at. The manager( very rude ) junaid, told me i would have the laptop back by latest tuesday the next week. I explained to him the urgency and asked him what would happen if i didnt have it back by his promised date ( 2 weeks after returning ). His words to me were “ if it is not back by tuesday i will give you a full credit “. It is now tuesday, i returned to collect the laptop and was told that it had only been despatched today and i could expect it on thursday. I spoke to junaid again asking for a refund as he was the one who promised the full credit and he then **** and told me he didnt say that. I have witnesses who were present at the conversation and witnessed him promising the full credit in the returns departmemt! This is unacceptable. He is rude and *********.
