Bad service

I am really disappointed in the Vodacom Fiber team. I have app**** for fiber through an promoter and this was approved. However, my fiber is not installed as yet as they are busy in the area with the installation. I seen that vodacom offer a 50MB service on this and want to take that offer. I done the application Friday the 17th of August, on Sunday the 19th I have phoned the call center to inquire on the application they advise it was approved. I then phoned again the 20th and spoke to Taryn, she advised that the order was declined now because I all ready have a line and cannot have a second one. I have asked them to cancel the first order so that I can take up the second order for the 50nb line. She advised that she will email me and send me the details and still no answer from them. Clearly they do not want customers to take up fiber with them. I rather have every thing cancelled with them and take an offer from some other ISP.
