Upgrade gone wrong

After probably 7 or 8 phone calls for more than a week now, my query I lodged about an Upgrade is still not sorted out. I was promised that my upgrade would be reversed in the next 24 hours, and that I will receive a phone call on Friday about other options with regards to my upgrade. I have asked to remain on the same contract as before with the same benefits, but it was not done! I have been customer of Vodacom for years and this was the worse service ever received from a online upgrade department. Can someone have my query sorted out a.s.a.p. Suzette
