Poor service

I bought 1 day data this morning and I only received an sms that the purchase was successful but the 3GB never came through. I called 135 and lodged a complaint and a later by the name of Dineo Modise gave me a reference and told me to follow up after one hour using the reference and I called after an hour and I found a very rude lady and she told me they is both she can do to return my airtime or data and I asked to her the reference Dineo gave me but she refused to track my query. I asked for a supervisor and she said she doesn’t have a supervisor. I can’t believe the level of disrespect I received from that lady. MTN is a big organisation to provide such a poor service. Even now I didn’t get my data and I can’t be ****** my hard earned money like that.
