No signal most of the time

So since I got my contract in January I have been having issues it took 6 months to get a technician out to chk my signal since then no one has bothered to ask me if the problem is resolved ... it is NOT resolved ... Is this considered a breach of contract? Cis I'm quite happy at this point to cancel the contract at vodacoms expense and take my business elsewhere ... It sucks having to have to go buy a new dual sim phone and take out a Telkom data contract just to be able to receive calls and use my data whenever Vodacom fails me ... Vodacom you owe me R4200 for the new huawei p8 lite I was forced to go buy cos u never call me back and 200pm for the Telkom data contract ... Your service sucks your products don't work as advertised and your shop reps need major further client relations and product services training ... Oh and get a new call centre too while you at it ... I will no longer waste my time trying to call you ... Call me rather at a time convenient to me between 10am and 2pm please... If you even bother to read this!!!!
