MTN worst service ever

Worst service ever!!! I upgraded my contract with MTN on 18 January to a MTN Mega Gig M with a bonus value of 1000 anytime minutes and 4GB anytime data.

I received my phone and pro-rata data and minutes on 4 February for only the Mega Gig M portion of the contract.

On 12 February when I was supposed to receive my full new contract, I only received yet again the Mega Gig M portion of the contract of *Gb data and 75 anytime minutes but no bonus value. I raised this with MTN on 12 February. I have contacted them several times, sent the adverti*****t and confirmation from the sales team that they upgraded me to the correct option and that the bonus value should be loaded.

The accounts department has billed me correctly for R1079 as per my choice of upgrade offer.

Finally MTN got back to me on 8 March to say my contract is correct and that it will be fixed. To date non of the bonus value have been loaded for February or March.

The call centre keeps on telling me they have escalated the my query, but nothing happens!
