Vodacom staff attitude ********* bad service

Vodacom service is terrible, we changed from mweb because we had endless problems with WiFi, slow and lagging all the time. We came to Vodacom, hoping for a better service and connection everything was perfect when they were getting the deal done, assured us that it would be better, we are in now about five months & we are now faced with the same issues? Gave them a call 2 weeks ago the guy said he would call us back the next day he never did, we went into the store today & this is the cherry on the cake of it all, the attitude and the most ********* service we recieved in the store, walked inn the store & we just get looked at by three different people just sitting there not wanting to help? The attitude is enough to put a person off ever doing business with Vodacom again I mean we are paying for the service, if it is not for your customers how would any one of them have jobs and how would you be in business? They spoke between each other in a different language & laughed who knows what was said only them ?Do you call this ethical or customer service?I want to know how we can cancel everything we have with Vodacom? their response call cancellation with a no care ATTITUDE!! what on earth? Perhaps you don't need customers
