Bad customer service from MTN

I have experience a bad customer service from Mtn since I have been a loyal customer of more than 15 years. My challenge is that I was called about the Wifi home router and informed that it was unlimited package, and it will be a month to month contract which can be cancelled anytime by taking the router to the nearest Mtn store.

I was told to call a different department from the call center to get assistance only to find that the number is not in service. I called again after 2 days to follow up only for the agents to hang up on me when I requested their names as I was told they have different departments.

I called mtn call center again to enquire about my router and had different answers from the agents I spoke to regarding the cancellattion by going to Mtn store only to find out that there is a cancelation fee and my package is 130g of data only for 24 months contract.

I had the hope of increasing my package as the package is not working for me anymore as the data is depleted within 2 weeks. I have emailed the Mtn complaints and they have not responded to me and it's been more than a week. They no longer appreciate the customers as they previously did in the past by providing excellent service and solutions as before.
