Terrible customer service

I am absolutely disgusted . I have been a loyal customer to vodacom Pinecrest mall in pinetown since 2008. Earlier this year I wanted to upgrade my wifi contract. Went into the store and was given an option for a 100gig Month to month contract. I then couldn't sign for it as the system was offline. I currently live in Portshepstone and made an appointment with on of the store consultants to come in again when the system was online. I even phoned the consultant (Charlene) the day before and she confirmed that everything was ready for me.

I then arrived at the store the next day, Charlene then started the process of canceling my existing contract to take out the new deal, as she had advised that this was the only way. 30min later my contract had been canceled , Charlene then checked the system and realized that the deal she had offered was not something I could get as it was a business contract. By now you can understand my disappointment and frustration, I had now wasted 2 trips from Portshepstone to Pinetown for nothing. The store manager then promised that he would resolve the problem and as a loyal customer, he would ensure that vodacom assists and reimburse me for costs encured .

It's now been 3 months and no answers. I called this morning only to be told that there is nothing they can do....

I am absolutely furious and demand answers from Vodacom.
