Expected to pay for benefits NOT received

Good day I would like to lay a official complain about the service we've received at MTN STORE JABULANI MALL. My husband and I bought the two Samsung A30s for R499 per month and we wanted the violet colors. We were told they had 2 in stock but upon our collection they only gave us one violet and a black one. Well we still took them cause it's just a color but that was not all.

Both our numbers were supposed to be transferred from prepaid to contract but only one number was done successfully. Apparently they activated the wrong number and now they've been promising to fix it but it's been over two weeks now and still no progress. They've never made means to contact us instead my husband keeps calling everyday and they keep telling him the same story that they'll call him back to no avail. Now someone out there is sitting with my airtime and data which I'm supposed to pay for. Now I ask, are we expected to pay at the end of the month for this kind of service? I haven't received my data nor airtime so should I pay my installment for nothing?

Both the stuff and the manager have not taken this issue seriously, they are laid back and relaxed telling us that it's still pending. They've refused to tell us who is responsible for the activation that was done. I have emailed mtn customer but no one has gotten back to me regarding this issue.... Maybe I should just return these phone, cancel the contract and move to another service provider. To think we have been loyal mtn customer for over 15 years but this is the **** service we receive.

Regards Angry customer
