Long wait for spectacles

I'm highly disappointed with the service received from Spec savers Gugulethu thus far. I got the eye test done and my specs were ordered, i got an sms to say they were ready the following week which was great but my issue now is that i returned my main specs for them to change the frame, i didn't think it would take longer than a month to do so since the first order came through extremely quicker. I'm struggling as i work infront of a computer every day so my eyes are suffering. This is now the 2nd month and my specs are still lingering somewhere. I have been calling to follow up but being told the hold up is at the Lab. Can this please be sorted out as soon as possible. Thank you
