Worst experience ever!!!!

Hello peter! I would just like to share my worst experience with the cell.c repairs department yesterday. It's been 8 months i have a contract with cell.c and within this 8 months ive had trouble with my Macer notebook twise! The first time it was a technical problem within the first month of having my Macer notebook so i took it back to the cell.c store where i took out my contact of which they replaced me with a new device. 8 months later i woke up one morning in order to do my reports of which i had deadlines to meet based on my job title and i had no access to my notebook and of which it said no bootable device. Obviously because i don't have any technical understanding i didn't know what this meant so i took it back to the same cell.c store where i took my contract with and they booked my device in to the repairs Centre to see why i have been experiencing this problems. The consultant in store that assisted me told me it would take about 2-3 weeks before i will receive my notebook again. Already this was a concern for me having to wait 2-3 weeks for my notebook to be sent back to me because i have only used my notebook for work purposes. Its now been more than 6 weeks! And still no answer. I told the consultant i don't want the same make/brand seeing that i have had trouble with my device twise before and that i have lost all confidence in this make/model and won't be satisfied if they are going to give me the same device. Yesterday i went back to the cell.c store to speak to the consultant for a follow up on what is happening as i have been waiting patiently for more than 6 weeks with no response or what will happen from here onwards. So the consultant kindly assisted me to contact the repairs department where my notebook was booked in because i could understand that it had nothing to do on store level. The gentleman at the repairs department was so disrespectful and when the consultant in store was trying to assist me to resolve thos matter because he could see i was getting irritated because the consultant at the repairs department was of no use!!! When the consultant asked the gentleman at the repairs department of he can speak to someone higher than him or a manager/assistant manager or team leader that might be able to assist him or give him the necessary answers with regards to my follow up the gentleman at the repairs department refused to let the consultant speak to a manager or anyone higher than him of which the consultant at cell.c store asked the gentleman several times to speak to a manager and still he wouldn't allow the consultant to speak to a manager! He gave all sorts of excuses saying that his manager is not there and that he stepped out, the consultant asked for the managers name at the the repairs department and the name of the gentleman that we spoke to at the repairs department of which he again denied us to give us that information. Obviously this call is on record and can be traced to hear how disrespectful the gentleman was towards me and the consultant making the consultant look bad because obviously he was the one that is facing and assisting me trying to give me the necessary answers that i am seeking. I am so angry, disappointed and disgusted by this poor service and don't think this is the level of service anyone should receive coming from the background of managing a store and giving the best customer service to the customers need. I had the leave the cell.c store unhappy, unsatisfied and leaving me in the loop because i don't know what the hell is happening or going on. Please can you help me resolve this matter before i action this any further to the necessary people that will address and take on this matter because i have been patient enough and can't pay for a device of which i do not have!
