No internet connection - ongoing!

Last week of June 2022, I had FOUR FULL DAYS of NO internet connection. MTN messaged me to say it had been resolved. It worked for a day and then once again I was not able to connect to certain websites that i need for business. THIS ISSUE IS NOT RESOLVED. I am still experiencing no or excessively slow internet connection. I cannot access some websites at all and speedtests confirm that the connection is VERY slow! I PAY MTN for internet connectivity! But i do not have any! I am self-employed and NEED to access internet to conduct my services. WHEN will MTN take notice and DO SOMETHING? and NOT IGNORE ME for days on end and then tell me all is working. IT IS NOT WORKING and I CANNOT WORK as a result!!!!
