Wi-Fi Data (promotion of Feb 2018)

On the 18/02/18 I 've upgrade to Wi-Fi ********** 57 which was a promotion of 10 G day and 10 G night. I've notice the data could not be correct and my daughter downloaded the app . Upon checking the data , I've discovered only 5 G day time data was loaded every month. I went into the MTN Metlife branch on Sunday the 27/05/2018 to query this and spoke to the lady that signed me up with the contact on the 18/02/18 Nikita and she advise me she had logged the complaint and will get back to me. On the 30/05/2018 no one from MTN phone me and I ve decided to go back to the branch on Wednesday to query the same thing just be informed that the complaint cannot be seen as a different system might have been used. No reference number was given to me on Sunday. Siebel at MTN gave me a reference number for the query which is 1- ********** 7942. As a long standing client of MTN I am not impressed with the service and would like the query to be investigate and feedback be given to me within a reasonable time.
