MTN service

I signed an Uncapped Contract on the 05th of October at MTN Columbine Square, last month my ZTE router couldn't connect for more than two week, had to drive to the store every time it gave me a Problem because the call center and the Technical support that I was transferred to couldn't solve the problem, this is so costly because I spend a lot petrol on petrol and the prepaid Data that I have to buy while I'm still waiting for the problem to be resolved at the end of the month they want a full payment while their product worked for 2 weeks . I'm writing this review because the same problem has started again I couldn't connect from yesterday, I contacted MTN was referred to the technical support that cannot resolve the problem, I went to the MTN store at Columbine Square. They also referred me to the technical support. This is so unprofessional. I've been with MTN on Contract for more than 15 years, but they just don't care. As long as they get you off the phone by giving you a technical support ref number. Which they don't even follow up to see if your problem is solved. I'm even thinking of going back to Vodacom.
