Breach of contract. No data service

So after being a customer with a number of contracts for several years I had issues with my data connectivity, no warning!! Called cell c was told I must fix the error once I dropped the call, 4 calls later I got told I'm being degraded from 4g to 2g, except everything my phone restarts it's back to no network, go to the store got told cell c is bankrupt, ok then got told I can cancel my other 3 contracts any time but or Tambo does not do contracts so greenstone here I come but nope you must call to cancel yourself, 1 hr later wait 30 days to cancel, fine but I still went to mtn 1 hr later new contracts and data connectivity at its best, cell c how dare you break your contract to me but I can't take my business elsewhere, I'm not leaving it here I'm meeting with my people next week to take this further I won't be forced to stay with a company that cannot provide a service at all!! Do you know how much data I'm using due to your nonsense of data roaming via another network not to mention a downgrade?? Your call centre doesn't even assist! But on the plus side go to another service provider still cheaper than staying with no network no service company!! Bye cell c!!
