A WEEK LATER STILL NO DATA

Good day, I took out a, data sim contract in April, I received my sin on the 27th with data loaded, pro rata, on Saturday 2nd May I did not receive my new monthly top up and logged a query With MTN, to date, 5 days later my query is still nog resolved and no data received. I logged a call via Facebook which was not even acknowledged, I received and email earlier the week asking if my query has been answered but to date no resolution, leaving me to constantly buy data. Please contact me asap to have this matter resolved I tried calling the 135 number but it tells me I have made an invalid selection when I want to speak to a consultant . Kind regards Berenice Geyer
