MTN customer care is HORRRIBLE!!!!

On 28 July'20, I sent a query to MTN via their website. It was in regards to my contract which expired and did not renew. Apparently I owe MTN some money, so I tried to make contact with them so resolve this matter. Firstly, I called the infamous 135 number which is purely automated with no longer an option to speak the "MTN champion". Hence the website route. According to the website they typically reply within 8 business hours which might be longer due to COVID'19 but two days later (30 July they reply to my mail to ask for my ID no. And I didn't hear from them until I contacted them again on the 06 Aug '20 with no reply to that mail until today. I then went on their twitter page to see if someone could assist. I was once again told that it will take 3-7 working days to get a reply from the legal department. I was unhappy with this and told them it was unacceptable and I demand a quicker response. They just ignored my request until I contacted them again a week later. Still no solution for my query. Yet, I take my hard-earned money and still spend with them buying airtime and data. They are so quick to run and take our money when you sign a contract with them. THIS IS UNACCEPTABLE MTN.
