Cell C and Vumatel suck

Spoke to Cell C on 4 April to change my Service provider on my Fibre line on 1 May. Cell C put an order to Vuma for new fibre line. I informed Vuma I have fibre just changing SP. Cell C advised Vuma as well and SP in fibre had to be changed. It is now the 15th of May and my fibre is still not switched on. Every time I phone Vuma or Cell C they have excuses longer than my arm. I have incurred huge data charges and both Vuma and Cell C feel just sit with their hands folded. Poor service from Vumatel and Cell C, get talking to each other and get this sorted. Cell C also promises calls back and I never hear back from Cell C unless I phone. Empty promises.
