Watch: Three major brands with pathetic service. EDGARS, GUESS and Bacher and CO.

I have bought a Guess watch from Edgars East Rand mall on the 29/11/2018. The guess watch is "waterproof" up to 50 Meters. I swam with the watch ONCE in a pool where the watch was maybe 3cm under the water. I took the watch off and when I looked at it again the watch had water in it where it proceeded to rust. I took the watch back to East Rand Mall on the 19/01/2019 and at first they didn't want to take the watch because they said it is water damage. I proceeded to point out on the Guarantee that states "Your GUESS Watch is guaranteed for a period of two years from the date of original purchase against all defects in material or workmanship. This guarantee does not apply to normal wear and tear or abuse or water damage. (unless marked water resistance)..." Thank goodness the watch was marked water resistant. Edgars then proceeded to take the watch and give me a for, Edgars special services register with a MAS no 006282. I've been trying for weeks to contact Edgars on the numbers they provided to me ********** but continently for them they never answer the phone. I then went into the store on the 21/02/2019 to get some feedback and they said to me they will contact me with feedback. I am still waiting. I then proceeded to phone Bacher and Co, on ********** and they could also not help me they did not want to take my details or even phone Edgars with any assistance. I have them the MAS no and they can’t pick anything up. I even phoned GUESS for their help seeing as it’s there faulty product on ********** and they can also not assist me. As you are aware GUESS is not a cheap brand but apparently there service is cheap and they don't live up to their standards. This is pathetic and cannot understand why I cannot get any assistance from the biggest brands in SA.
