Poor pathetic service and complaint management by MTN

I on a day contract but rather under false impression. I have a 20gigabyte contract per month which is a 10 gigabyte daytime and 10 gigabyte night time and about 30gig of you tupe. The technicality here is that if you have exhausted your day and night data allocation you cannot access your you tube data. I found that out yesterday. What is the use of allocating these data in a contract if it is like this? I haven't even received a contract to review despite asking MTN employees on numerous occasions. They just wipe their hindsight in your face. I found the employees of MTN to be in general not properly equipped to do their work they give information selectively and will only reveal when you have a query. It seems as if their training is orientated to be to the disadvantage of the client. You can go onto Facebook and onto their site and can see the negative comments of disgruntled clients. I rate MTN as a first-class legal ********ly exploitative network who does not have the interest of the clients at heart but rather numbers. Subjectively a zero on any positive contract. My professional opinion and rating is on par with a dead snake who still causes misery like in my case. I am battling them with "EARLY UPGRADE SETTLEMENT PENALTY FEE WHICH THEY HAVEN'T INFORMED ME ABOUT AND THEY PROTECT EACH OTHER
