Bad customer service, bad overall connection and no ownership by MTN

My LTE connection has not been working for the past 10 days. I have called MTN, I have reached out via their social media platforms. I was told my issue has been escalated to the coverage team last week Thursday, the turnaround time for feedback quoted was 24 hours. I have followed up, only to he told I will he attended to shortly. That time they do not miss debiting my bank account. I work from home and I have had to pay for an alternative connection even though I am still paying MTN. I just want to cancel the LTE connection and join a company that actually cares about their customers and their customers need for a working connection. I am just done running around trying to get MTN to assist.
