Struggling to get refund

<p>I activated the 1GB Data Extenda on 1 February 2016 and decided i don't need it anymore during March. when i phoned in the consultant told me to rather phone on the last day of the month since they have already charded me for march. I phoned in on the last day of march and the consultant said he has deactivated the service but was surprised to get an sms on the 1st of April to say that my 1GB data extender has been added.I immediately phoned in and the lady said nothing was deactivated the day before and she immediately deactivated the service for me and she send me an sms to confirm that. the lady told me because its already the first of the month, ive already been charged for the service, she advised me to phone on the last day of April so that i can request a refund which i did but i did not get help. i phone again on the 10 of May and the consultant promised to escalate the queiry but to this day i have not received any response. the reference number for the queiry is ********** 989. Could i please received assistance regarding this matter.</p> <p> </p>
