Repair taking so long should let cell c buy me out

Dropped off a water damaged phone to be repaired mid-April. First it was sent off to JHB to be repaired without a serial number, which should have been flagged initially as it couldn't switch on, and I had to come in to provide this. Back from JHB to CT, then back to JHB, then on its way to the third party, Huawei. I have not once received an update- you'd think an sms service would be a good idea to keep customers updated?- and have to phone in regularly to find out what is going on. Over 8 weeks of waiting, no communication, and no idea when it will be returned. Would rather let Cell C buy me out of my contract at this rate, if this is considered normal service delivery for Vodacom.
