Pathetic service!!!

I took out a new LTE Home contract from MTN in December 2021. It took MTN two weeks just to activate my sim card. Once the sim cards was activated the brand new ZTE router was faulty and kept is disconnecting from the internet. I then had to book the device into the repair center. They told me it will take 7 days. I would call the repair center everyday and they would keep telling me to call tomorrow. Three weeks went by until I got an approval on the warranty assessment. The new device needs to be couriered from the store where I took out the contract. I have not yet received the device and this will be the second month that I am going to be paying for something that I haven't used. Pathetic service!!!
