Unhappy customer and pathetic service

Hi my name is Silindile,I have a very bad experience with MTN,I took a home wifi in May 2024 cause I was working from home,I went back to the office in June 2024,so I returned a wifi in Pavilion and was advised that I can only return it after a month,I then went back after a month to return it and was assisted by an Indian guy by the name of Yogan Naidoo who took the wifi and advised me that he cancelled my contract,I kept getting text messages and statements via email which stated that I owe them,in September 2024 when I app**** for a bond I was advised that MTN handed me over ro ITC,I called MTN and was advised to go to the Pavilion branch which I did the very same guy(Yogan Naidoo) advised me that he will send my query to their legal dept to remove me from ITC and I will never receive any more statements and text messages from MTN,I received a letter stating that I don't owe them anything and my name was removed from ITC,and guess what,I received another statement and a text message a month letter which ai sent ro Yogan Naidoo via email ,but he didn't even reply to my email,In December I got married and relocated to North West so I can't go to MTN Pavilion in Durban ro enquire the statements and text messages that I am still receiving,I am applying for jobs here in North West and do ITC check ,MTN is unprofessional and I don't wish anyone o use MTN anymore cause they will be in the same problem in future,MTN doesn't care about their customers once they cancel contracts with them, all they want is business ,they don't do follow ups and don't care at all,my contact no is ***
